The Attempt at a Solution
I subtracted equation 2 from equation 3 and came up with the following matrix
2 4 -2 -1
1 3 1 2
0 0 0 1
1 -2 1 2
It seems to make sense to pivot around the 1 in the third equation. I tried it and got 5 which I know is not that answer using an online Matrix calculator and my professor.
