  1. Math:
    If we take away 9 CDs, then they sold equal quantities, namely (41-9)/2=16 each.
    So John sold 16, and Paul sold 16+9=25 CDs.

    Algebra:
    Let x=number of CD's sold by John, then Paul sold x+9.
    Equate total:
    x+x+9=41
    2x=41-9
    2x=32
    x=16 (John)
    x+9=25 (Paul)
