    4x + 2y = 4

    6x - 8 = - 2y

    Both equations are divisible by 2, so divide both sides of both equations by 2.

    2x + y = 2

    3x - 4 = - y

    Since the second equation has - y on one side, we can multiply both sides by - 1 to solve for y.

    y = - 3x + 4

    Now we substitute y of the first equation with - 3x + 4.

    This is the substitution method.

    2x + y = 2

    2x - 3x + 4 = 2

    -x + 4 = 2

    -x = - 2

    x = 2

    Now we substitute 2 for x in the first original equation and solve for y.

    4x + 2y = 4

    4 (2) + 2y = 4

    8 + 2y = 4

    2y = - 4

    y = - 2

    The solution is x = 2 and y = - 2
