The Attempt at a Solution
[/B]
I apologize in advance, as I'm not sure how to make these matrices look good (will need to look up LATEX, so I can present my matrices better).
The elementary row ops that I chose to do were as follows:
R2 + R1 --> R1
R2 <---> R3
R3 + R2 -->R2
R1 + R2 --> R2
2R3 --> R3
R3 + R2 --> R2
This gave me the following matrix, which is not the answer, but is my best try:
a =
3 1 -1
5 5 0
2 2 1
