My teacher that when you multiply you have to do it from the left or you will get a different answer... My answer was X=[1.48, .8_.2, 0]

You are correct. You have to multiply on the left to get the right answer. Matrix multiplication is not commutative, so the order of multiplication is really important.

yes greeneyes  you (and joemath) are right. you MUST multiply on the left or you will get the wrong answer. I believe across has the wrong answer here. e.g if: \[AX=B\]then:\[A^{1}AX=A^{1}B\]therefore:\[X=A^{1}B\]
