You can
put this solution on YOUR website!Solve the matrix Eqauation:
[9 7] [9 2] =[72 99]
[11 9] X + [4 11] [77 130]
------------------------
These are a mess to show the work.
-------------
You have an equation of the form
AX + B = C
where A,B, and C are 2x2 matrices
-------------
You need to subtract B from both sides to get:
AX = [C-B]
---
Then you need to multiply both sides by A^-1
to get
X = A^-1 [C-B]
======================
Hope that helps.
