    I don't know how your son is supposed to do this.

    Here's a simple algebra solution. Let x = the miles that Jan and Myra each ran.

    x + x + x - 8 = 64

    3x - 8 = 64

    3x = 64 + 8

    3x = 72

    x = 72/3

    x = 24



    24 - 8 = 16

    this makes no sense to me and won't to my child either. the instructions for solving, are try 3 numbers that add to the total with 2 numbers equal and the other 8 less then revise numbers till you get the answer.

    64÷2=32-8=24-8=16
