    If you mean trying to figure out what "y" is without the 4. first you have to get the 4y by itself. To do that, subtract 8x from the left side and subtract it from the right side.

    -4y=20-8x

    Then subtract everything by - 4

    y=-5+2x

    I believe that is the answer (bolded part)

    -8x - 8x

    -4y=20-8x

    divide each side by - 4

    y=-5+2x
