I do not know which algorithm they gave you in class by switching first and last row
1 1 -3
2 4 -1
4 1 2
1 1 -3 kept row1
0 2 5 row2 - 2times row1
0 -3 11 row3 - 4times row1
1 1 -3
0 1 -16 (row2 + row3)times -1
0 -3 11 kept it
1 1 -3
0 1 -16
0 0 -37 row3 + 3times row2
1 1 -3
2 4 -1
4 1 2
1 1 -3 kept row1
0 2 5 row2 - 2times row1
0 -3 11 row3 - 4times row1
1 1 -3
0 1 -16 (row2 + row3)times -1
0 -3 11 kept it
1 1 -3
0 1 -16
0 0 -37 row3 + 3times row2
