2 -3..-2
1 2..13
--------------
Divide thru 1st equation by 2 to get:
1 -3/2..-1
1...2...13
-------------------
Subtract 1st row from 2nd row to get:
1 -3/2...-1
0...7/2..14
------------------
Divide thru 2nd row by 7/2 to get:
1 -3/2...-1
0...1.....4
----------------
Multiply 2nd row by 3/2 and add to 1st row to get:
1...0.....5
0...1.....4
