I don't know of a calculator that can do that for you, its transposition, you have to get x on its own to find its value which in this case is 0.9

what you do to one side you do the oposite to the other for eg
if 10x+2+45-56=0 then
10x+2+45=56 we moved -56 over the = to make it +56 then
10x+2=56-45 then
10x=56-45-2 which is the same as 10x=9 then

10x means 10 multiplied by x, so to move the 10 over it becomes division.

How do i solve for the solutions to the simultaneous linear equations on the fx-115es? I don't know how to set up the calculator to do it. 10x-3y+10z=5 8x-2y+9z=3 8x+y-10z=7

Select the EQN computational mode 5:EQN
For system of linear equations in 3 unknowns select 2: in the screen below.
Arrange the variables in your equations in the same order (x first, y second, and z third).
The coefficients to enter in the editor are the factors of the variables: In your case a_1=10, b_1=-3, c_1=10, d_1=5, a_2=8, b_2=-2, c_2=9, d_2=3; a_3=8, b_3=1, c_3=-10, d_3=7.
To enter d_1, d_2, and d_3 you will have to scroll to the right to reach the cells where they should go.
Once finished entering the coefficients, press EXE to get the solutions. You may have to use the arrow Down to display the y- and z-solutions.
I verified that the matrix is non-singular and the system has a solution. In fraction form
x=27/53, y=-1 and 22/53; finally z=-23/53

First thing to do, before you enter the value of the equation to your calculator multiply the first term((1/3x+5) from the second term(1/3x+5) to make your answer simplified.Then after that you will observed that your answer look like in this pattern AX2 +BX+C it means that the equation is in general form of quadratic equation. So, in your problem,we are looking for a value of X1 and X2,when you used your calculator in solving this problem, First On you calculator then look for the mode then press it after that look for the equation(EQN).Then from the side of the word EQN there is a corresponding number to press,from my calculator it is number 5..Then press it.After you press it, there is a equations choices,look for the equation AX2 +BX+C then press it(given number to press). Now,enter the value of A, B and C from your simplified answer. After pressing the value of A press = sign from your calculator same as B and C.After you enter all the value of A,B and C continuously press = sign from your calculator till you get the answer, the value of X1 and X2.

How to solve equtions like that: (X + Y)^2 and get result like that X^2 + 2XY + Y^2 IS THER ANY WAY TO DO THAT


Yes, this is basic algebra but, can just as easy be explained by using regular numbers.

For example:

(3+2) ^2

This basically means (3+2)*(3+2)

Then you just multiply the product of the above.

3*3 + 3*2 + 2*3 + 2*2 = 25

Now, when you are working with symbols, the same principle is used solving it. In the example you gave:

(X + Y)^2 can be written as follow:

(X + Y) * (X + Y) =

Now, again, just multiply out the product of the equation written above and you will get the answer.

X^2 + XY + XY + Y^2 Hence = X^2 + 2XY + Y^2

Hope this can be of help.

Feel free to let me know if you need further assistance.

Kind regards

How to input cos x=0.75?

I assume that if you want to input the equation it is with the intent to solve it. If that be the case then what follows will help you input and solve any equation (linear, quadratic, trig, etc.)

Make sure the calculator angle unit is the same as your problem requires (degree, radian, grad). Here are some screen capture to help you. Change the equation to yours. 21c8779.jpg4b6c1ea.jpg
To enter the equation in screen above, use the right arrow.

You have to enter an initial guess on line X=, a default value may be supplied by calculator: It depends on last value stored in X. Once a value is entered press the F6 key to SOLV
Press F1: Rept if you want to solve another equation.

-5(n-2)=4(2n+3) put in ti 89 how?

To enter this equation on a TI89Titanium is rather trivial: You use the keyboard and the [ALPHA] key to enter the variable (or unknown) n.
The question I am asking you is this: "What do you intend to do with the equation once it is entered?"

As you can see on the screen capture I am enclosing, if you just want to enter it and if n does contain a value already, all the calculator will do is to echo the command without modification. Obviously this is not what you want.

The screen capture shows you two other commands you can use solve( and expand (.

That should answer your question concerning how to enter the equation (look at the command line) and maybe help you decide what you want to do with the equation once it is entered.

How do i program formulas into my ti-83

To begin a program, press the "PRGM" button and create a new program, naming it however you like. Now, the best way to have it evaluate your numbers as a formula is to begin with a prompt. Press "PRGM", then toggle to the "I/O" menu from the selections at the top, then select option 2, "Prompt". On the same line, list the variables you wish the formula to evaluate, separated by commas. Press "ENTER" to begin a new line, then type out the formula, placing the corresponding letters in their proper places. Instead of an equal sign, use the "STO>" key and then another letter variable using the "ALPHA" key and any letter. Finally, press "ENTER" to begin a new line, press "PRGM", browse "I/O", and find option number 3, "Disp", followed by the letter variable you specified as the answer to your eqution.

This is an example illustrating the equation, 'F=ma'

:Prompt M,A
:Disp F

To start the program from the home screen, press "PRGM", select "prgmFORCE", and enter it on the home screen. You will be faced with a query, as illustrated below:


Simply enter the value you desire for each variable as it appears, and the calculator will evaluate and display your solution.

Ti 84 plus problem

The calculator only displays from -10 to 10 on the x and y axes, and both of your lines are outside of that range. However, it is easy to change that.

1. Hit the gray "WINDOW" button that is directly under the screen
2. Change "Xmax" to 150
3. Change "Ymax" to 200

Remember to change both of those values back to 10 when you are done with this problem!

Here's how to graph it:
1. Hit the "Y=" button
2. Enter your first equation after Y1, and your second equation after Y2
3. Look over both the equations to make sure you typed them correctly
4. Hit the "GRAPH" button
5. If you don't see the intersection you will need to adjust Xmax and Ymax again
6. Hit Hit "2ND" and the "TRACE" to bring up the "CALC" menu
7. Scroll down to "intersect" and hit enter
8. Hit enter 3 times (You use the first and second curve options when you have more than 2 lines)
9. It should display the coordinates at the bottom
10. I got (76, 142.1) for the intersection

Thanks for asking this question! I used to do this a much harder way, but while I was calculating the answer to your question I hit a wrong button and accidentally found this method!

My calculator will only graph one graph at a time.

This is simple... Back up all RAM, (press second+, then 2, then 1, press enter to back up something if backed up it will have a star by it) Then clear your RAM (pull out your batteries while the calc is still on or press second+, then 7, then 1)
Hope this helps!
