    Subtract 63.5 from both sides. The answer is 6.5 inches.

    Step-by-step explanation:

    Set up an equation:

    70 = x + 63.5

    Where x is the number of inches Mary needs to grow to be the same height as Tonya

    Subtract 63.5 on both sides:

    70 = x + 63.5

    -63.5 - 63.5

    6.5 = x

    Therefore, Tonya is 6.5 inches taller than Mary.
