Question 162532: Find matrix X:

4. [3 4] [-3 -2] * X = [10 -10] [-8 8]
I have no clue where to even begin with this, I apperciate any help you have to offer me, id love to see the steps and correct answer. Thank you so much!

First find the inverse of your first matrix, which we'll call [A].
[A]=
and the inverse of A called [A]inv.
[A]inv=
and then matrix multiply both sides to solve for [X].
.
.
.
The problem would then look like this,
[A][X]=[B]
[A]inv[A][X]=[A]inv[B]
[I][X]=[A]inv[B]
[X]=[A]inv[B]
.
.
.
So we do the matrix multiplication,
[X]=
[X]=
