Find matrix M such that AM=B when A = 1 2 3 2 1 7 2 2 7 B = 0 0 1 1 0 1 0 1 1 0 1 0 I think side by side Gaussian Elimination is used somehow.

Can you compute and multiply on the left by that?

Same idea but a little faster: Replace the identity matrix on the left by the matrix B: and do the row operations, as Soroban shows, to reduce the matrix, A, to the identity while applying those same row operations to the matrix, B.
