    There is one solution (x=2, y=0)

    Step-by-step explanation:

    y=4x-8

    4y=4x-8

    Divide the second equation by 4

    y = x - 2

    Set the two equations equal

    4x - 8 = x-2

    Subtract x from each side

    3x - 8 = - 2

    Add 8 to each side

    3x = 6

    Divide by 3

    x = 2

    Now find y

    y = x-2

    y = 2-2=0
