Henri solved the system of equations below. What mistake did he make in his work?
3x + y = 6
x  2y = 2
y = 6  3x
x  2(6  3x) = 2
x  12 + 6x = 2
7x  12 = 2
+ 12 +12
x = 2
3(2) + y = 6
6 + y = 6
6 6
y = 0

Besides not explicitly showing that 7x=14 in solving for x, I don't see anything wrong here. The solution works.
