Solve for X:
We know we need to use this method , which are two types:
Type 1: AX = B and Type 2: XA = B
But the issue is we must first do operations that will set it up to these two forms.
We know that we must remove the fraction because Matrices cant divided. I would assume we would times both sides by A to remove the fraction. But the problem is getting those two forms. With these operations.
Here is my working out: But i don't believe they're correct.
So my problem is I cant get AX = B or XA = B. So I can solve for X, If you want anymore details please tell me and I hope posted this in the correct section as well , I apologize if I didn't.
