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.
