Homework Statement
Find the 3x3 matrix X such that XA=B, where
The attempt at a solution
I understand how to do AX=B just fine, but XA=B is confusing me. I tried doing [x y z] A, but not sure if that's even right or what to do after that. Yes, I know it can be solved using inverses or whatever, but the professor does not want us to solve it that way (haven't gone over inverses yet).
The solution for X such that AX=B involved finding individual columns, so does that mean XA=B will find the individual rows?
Any help is appreciated!

Code:
1 1 1
A= -1 0 -2
1 0 -1
1 3 0
B= -2 1 -2
1 4 -1
