John and Paul work together at a music store. In one afternoon, they sold a total of 41
CDs. If Paul sold 9 more CDs than John, how many CDs did John sell?

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.
Let x=number of CD's sold by John, then Paul sold x+9.
