    One Solution

    Explanation:

    7 (y + 3) = 5y + 8

    Simplify both sides of the equation

    7 (y + 3) = 5y + 8

    (7) (y) + (7) (3) = 5y + 8 (Distribute)

    7y + 21 = 5y + 8

    Subtract 5y from both sides

    7y + 21 - 5y = 5y + 8 - 5y

    2y + 21 = 8

    Subtract 21 from both sides

    2y + 21 - 21 = 8 - 21

    2y = - 13

    Divide both sides by 2

    2y = - 13

    2y / 2 = - 13 / 2

    y = - 13 / 2

    -13 / 2 = - 6.5

    y = - 13 / 2 or - 6.5
