Let's rewrite as

7(3x+5) = 8x -1(1-4x)

Let's distribute

21x + 35 = 8x -1 + 4x

collect like terms

21x + 35 = 12x -1

Put all the x's on one side by subtracting 12x from both sides

21x -12x + 35 = 12x -1 -12x

simplify

9x + 35 = -1

get all the constants on the right side

9x + 35 - 35 = -1 - 35

9x = -36

divide both sides by 9 to get x by itself

9x /9 = -36/9

x = -4

check in original equation

7(3(-4)+5) = 8(-4) -(1-4(-4))

7(-12+5) = -32 - (1+16)

7 (-7) = -32 - (17)

-49 = -32-17

-49 = -49

7(3x+5) = 8x -1(1-4x)

Let's distribute

21x + 35 = 8x -1 + 4x

collect like terms

21x + 35 = 12x -1

Put all the x's on one side by subtracting 12x from both sides

21x -12x + 35 = 12x -1 -12x

simplify

9x + 35 = -1

get all the constants on the right side

9x + 35 - 35 = -1 - 35

9x = -36

divide both sides by 9 to get x by itself

9x /9 = -36/9

x = -4

check in original equation

7(3(-4)+5) = 8(-4) -(1-4(-4))

7(-12+5) = -32 - (1+16)

7 (-7) = -32 - (17)

-49 = -32-17

-49 = -49

You can solve it with following method.

5x+3y=6 2x-4y=5

So 5x=6-3y so 2[(6-3y)/5]-4y=5

So x=(6-3y)/5 so 12-6y-20y=25

so -26y=25-12

so -26y=13

so y= -(1/2)

2x-4y=5

so 2x=5+4y

so 2x=5+4(-1/2)

so 2x=(10-4)/2

so 2x=6/4

so x =3/2

The value of x=3/2 and value of y= -1/2

Let me know if you need further assistance.

Hi,

This calculator does not have a Solve function or a solver. However this example of yours is very simple that you can do it by hand. If you do not mind I will show you how to solve it. Not everything needs a calculator.

You want to solve for x. OK

You want to solve for x. OK

- Start by gathering similar terms 4x-x =3x; -13+5 =-8
- Rewrite your equation as 3x+1=2x-8
- Make the +1 change side while changing its sign
- 4x+1 -1 = 2x-8 -1 or 4x=2x-9
- Make +2x on the Right hand side go to the left hand side, changing its sign in the process 4x-2x=-9 or 2x=-9
- Divide both members by 2. This gives
- x=-9/2 or -4.5 if a decimal result is required.

Unless I am failing to understand your problem, just combine like terms to get:

9x^2+2x+4 and then enter those coefficients into the quadratic solver.

That will get you the two answers -- both of them will be complex.

If you wanted to turn those two answers into factors (complex) of the original equation simply

change the signs on each and put an x in front.

Of course, the quadratic formula would also work.

use the simultaneous equation solver software available on ur ti-89 and enter the equation in the form of augmented matrix and you will get ur answer.

just a simple multiplication
solve first which is inside the brackets
9x(-7)=-63
3x5=15
(-63)-4x15
-67x15
-1005
.. i think am rite..

Srry my friend the ti 83 is no magnificent Ti-89. meaning: you have to solve it yourself. There is a method for graphing though. Set the equation equal to zero and then plug the stuff on the other side of the equation into a graph by pressing y= and then typing it in. Then hit graph. Wait for the graph and then hit 2nd calc and select zeros. Bring your cursor using hte arrow keys close to where the line hits the x axis and press enter and then do the same except to the right of that point and then press enter twice and it will display the y which should be the answer

There are quadratic formulas for calculators programmed in tibasic for the calc but other than that there is no way to solve it

Usually answered in minutes!

assume 9x + 2x = a

take X as common outside

so x(9+2)=a

which can be written as

x= a/11

problem solved.

you say me the value of a

i wil tell you value of X...

how is this..

I will probably need sometime to figure this one out :D
