Inverse Matrix Proof
I'm having a bit of a struggle with my assignment.
I'm supposed to find what is x in AxB = (B-1A-1)-1 .
I'm stumped at what to do with this. My friend said that x is I (identity matrix), but he is unable to prove it as well. My linear algebra class just recently started doing this topic and I haven't fully absorbed the subject yet.
Any hints or tips would be helpful though.

Hi, you should try to simplify the right hand side, starting with the outermost -1. What rules do you have for the inverse of a product of matrices?
