I am doing some homework, but I am stuck on this problem.
- $-x+y=-2$
- $-3x+2z=13$
- $2x-2z=-6$
Here's my work:
That wasn't accepted. I then threw it in matlab, to try to work my way towards the right answer, and got $(-1, -3, -2)$ and that wasn't right either. Further, I found a matrix calculator online and that gave a different answer that was wrong also.
Can anyone tell me where I went wrong in the above picture?

$-6+(-2)(2) = -10$, not $2$.
Simple arithmetical error in bottom right entry in first line.
