    The difference of five and five y
    5 - 5y

    eight and two y
    8 + 2y

    The phrase is the same as means equal to. Set 5 - 5y equal to 8 + 2y for our final algebraic expression
    5 - 5y = 8 + 2y

    If the problem asks you to solve for y:

    Add 5y to each side:
    5 = 8 + 7y

    Subtract 8 from each side:
    7y = -3

    Divide each side by 7:
    y= -3/7
