Add (-2 * row1) to row2
1|. 1|.. 0|..1|
0| -2| -1|.-2|
0|.1 |..2 |..-2
------------------------------
Divide row2 by -2
1|1|..0|1
0|1|1/2|1
0|1|..2|-2
------------------------------
Add (-1 * row2) to row3
1|1|...0|1
0|1|1/2|1
0|0|3/2|-3
-----------------------------
Divide row3 by 3/2
1|1|...0|1
0|1|1/2|1
0|0|..1|-2
----------------------------
Add (-1/2 * row3) to row2
1|1|0|-1
0|1|0|2
0|0|1|-2
