The first way is through an equation: 12x = 72 (To get x by itself, we divide 12 on either side.) (12/12 = x) (72/12 = 6) ∴ x = 6; there are 6 shelves in the bookcase. There are two ways to do this: random numbers, or an equation.    Check the answer:   12 * 2 = 24   12 * 3 = 36   12 * 4 = 48   12 * 5 = 60   12 * 6 = 72 Therefore, there really are 6 shelves in the bookcase.
