How do i use this for algebra equations, putting in varables and such

8m - 6 =2(4m - ????
You are trying to fetch the common part from the equation.
Let's know what is 2 here? It is the common part right?
Now dividing 2 from 8 and 6.
What the process left behind??
It is - 4 and 3

So the final equation you are looking for is:
8m-6=2(4m-3)

Diann, there are several mathematician types here who like to solve algebra equations. They often hang out in this forum

I don't myself have any knowledge about entering stuff into that calculator, but I hope someone else does.
.

Yes it can be keyed in.
To enter the X, use the ALPHA followed by ). To enter the = sign, you use [ALPHA][CALC].
To use the calculator to SOLVE an equation you must enter the equation, then press [SHIFT][CALC] to (SOLVE). You will be prompted to solve for X. Follow it from there.

As to the case you show, the constant terms will drop and you are left with 26X=0, and the solution is X=0.

Note: The calculator cannot do algebra with letter symbols. It does not have a Computer Algebra System or CAS.

I do not own that calculator so I checked the manual. In the chapter Manual calculations it explains the use of matrices but not a single reference to eigenvalues or eigenvectors. I looked also in the advanced functions chapter but nothing on eigenvalues. I believe you will have to use the general algebraic methods for calculating eigenvalues: characteristic polynomial and its solutions. Set up the equation det (Mat A -lambda Mat I)=0 where A is your original matrix and I is the Identity matrix with same dimensions as A. The determinant will give you a polynomial equation in the eigenvalue lambda. the degree of the polynomial will be equal to the dimension of the matrix. You might want to feed the equation to the polynomial solver to find some eigenvalues.

this is a simple algebraic equation in which we have to calculate the value of 'x' using simple operations

7+(9-5x)=5(2-x)


step 1(pen the brackets) 7+9-5x=10-5x
step 2(add 7 and 9) 16-5x=10-5x

now as 5x gets cancelled both the sides of the equal sign therefore no solution of this algebraic equation exist.

You cannot. The TI-30XA is a simple calculator lacking any symbolic algebra or equation processing. However, if your task is "given a value for x, what is the value for y" for the equation you give, you can rearrange it a little:



Thus, if you want to determine the value of y for x = 16, key in 5 [-] 16 [÷] 4 [=] and get the result y = 1. To double check, substitute x and y in the original equation:
16 + 4 x 1 = 16 + 4 = 20.

It is always risky to try to answer a question about a calculator of an undisclosed model.
To be able to symbolic algebra (with variables), one needs a calculator with CAS (or Computer Algebra System). These types of calculators are special graphing calculators. ( Not all graphing calculators have a CAS.)

To get back to your question: No, you cannot do algebra with a mere scientific calculator even a recent one. All you can do is define an equation with variables A,B,C,D, Y and X and press the Solve button if it exists. The calculator will ask: Solve for X?. If you say yes, you will be prompted for the values of all letters (A,B,C,D, Y) in your equation and the calculator will search for the value of X, that makes the left side of your equation equal to the right side.

It will display the X-value and the difference L-R.

Divide the first equation by 2, the second by 6 (i.e. the number that comes before the x)

cryshug24 the mode(s) you want to use is mth IO and line IO for algebra. push the shift mode then #1. to write out a long equation push shift mode #2. you have to keep playing between the two modes to get the correct answer.

Type it like this: solve( equation1 and equation2 and moreEquations, {list of variables to solve for})

Put all of your equations right after the opening parenthesis separated by the word and, then a comma, then within curly braces each variable you want to solve for each separated by a comma.
