You do understand that A^{-1}A= I, right? So just go ahead and multiply those together and see what you get!
For example, Multiplying the second row of ^{A^{-1}} by the first column gives 2+ 3x= 4= 0.
The question is attached.
The main thing of the question is for me to understand the concept.
So to find the values of (x,y,z) I would have to find the inverse of the inverse matrix. I think I'm supposed to use the supermatrix method or the co-factor method? But how would I go about doing that?
If I use the supermatrix method, there's no way I can reduct the second row to [0 1 0]. The co-factor method would just give me lots of unknowns...
