    Nothing. Now we have the equations:

    -2y = 2x - 4
    y = -2x + 6

    So add them:

    (-2y + y) = (2x - 2x) + (-4 + 6)

    How did you get 2? You need to slow down.

    Try solving one more time.

    -2y = 2x - 4
    y = -2x + 6

    So add them:

    (-2y + y) = (2x - 2x) + (-4 + 6)

    -y = 2 => y =-2.

    So, (-2) = -2x + 6 => x=4

    The answer is (4,-2).
