-1 -3 | -17
2 -6 | -26
add 2x#1 to #2:
-1 -3 | -17
0 -12 | -60
subtract #2 from 4x#1:
-4 0 | -8
0 -12 | -60
Now divide so the diagonal is all 1's:
1 0 | 2
0 1 | 5
x=2, y=5
Solve the system using an augmented matrix.
-x-3y=-17
2x-6y=-26
Can someone please explain what I am supposed to do in this problem?
