    X is larger number

    y is smaller number

    x-y=5

    2y=x+18

    1.) Find formula for x

    2y = x + 18 | - 18

    2y - 18 = x

    2.) Find the value of y

    x-y = 5 | plug in the formula for x

    2y-18 - y = 5 | combine like terms

    y - 18 = 5 | + 18

    23 = y

    3.) Find the value of x

    2y = x + 18 | Plug in the value of y

    2 (23) = x + 18 | Distribute

    46 = x + 18 | - 18

    28 = x
