2 +1 +2 =0
4 +3 +2 =2
2 -1 -3 =0
Divide row1 by 2
1 1/2 1 0
4 3 2 2
2 -1 -3 0
Add (-4 * row1) to row2
1 1/2 1 0
0 1 -2 2
2 -1 -3 0
Add (-2 * row1) to row3
1 1/2 1 0
0 1 -2 2
0 -2 -5 0
Add (2 * row2) to row3
1 1/2 1 0
0 1 -2 2
0 0 -9 4
Divide row3 by -9
1 1/2 1 0
0 1 -2 2
0 0 1 -4/9
Add (2 * row3) to row2
1 1/2 1 0
0 1 0 10/9
0 0 1 -4/9
Add (-1 * row3) to row1
1 1/2 0 4/9
0 1 0 10/9
0 0 1 -4/9
Add (-1/2 * row2) to row1
1 0 0 -1/9
0 1 0 10/9
0 0 1 -4/9
