    1) 18+2y+4+10+2x+10

    2) 42+2y+2x

    3) 42+2x=-2y

    4) - 1 (42-2x=2y)

    5) (42-2x=2y) / 2

    y=21-x

    Step-by-step explanation:

    1) Original equation

    2) Combine like terms

    3) Since the problem is asking to find the value of Y, Isolate it

    4) Multiply by a negative to make Y positive

    5) Since what we have left isn't in simplest form, divide by 2

    What is left is y=21-x or y=-x+21
