2x-3y=-2
3x-4y=9
Answer by pie90010(44) (Show Source): You can put this solution on YOUR website!
set up your 2x2 matrix
[ 2 -3] [x] = [-2]
[ 3 -4] [y] = [ 9]
So you can't divide matrices, so just multiply by the inverse, its the same thing
Its a lot easier to use a calculator here
[A]^-1 [B]
Your a answer would end up
