I can't find any tutorials because they're all on linear equations... or is that related with these equations?

Answer 3

Yes

Answer 4

I'm the one who asked the question by the way, and yes I know

Answer 5

ok. You can just treat it as an algebraic equation an isolate M on one side.

Answer 6

So I multiply every number in the first matrix
5 1 -8
by 4?

Answer 7

It's an equation. You need to multiply both sides by 4.

Answer 8

oh no, I subtract
5 1 -8
by the other matrix -2 -1 3, THEN I multiply?

Answer 9

Both work. Subtracting is a little cleaner.
