    M + 9 = 13 or 13 - 9 = m

    Therefore, m must equal 4

    m = 4

    Let x = Tom’s allowance

    Let x/2 = the amount he spent going to the movies.

    So x - x/2 = the amount he has left after she went to the movies

    he washed the car and earned nine dollars, so you’d add that amount in

    x - x/2 + 9

    the amount he has left over is 13 dollars

    x - x/2 + 9 = 13

    Now you solve for x

    x - x/2 + 9 = 13

    x/2 + 9 = 13

    x/2 = 4

    x = 8

    His allowance is $8

    To check your work, plug 8 into the equation:

    8 - 8/2 + 9 = 13

    8 - 4 + 9 = 13

    13 = 13
