The sum of two consecutive integers is 15. What is the product of the two integers?
x = 1st consecutive integer
x + 1 = 2nd consecutive integer {consecutive integers increase by 1} x + x + 1 = 15 {the sum of two consecutive integers is 15} 2x + 1 = 15 {combined like terms} 2x = 16 {subtracted 1 from each side} x = 8 {divided each side by 2} x + 1 = 7 {substituted 8, in for x, into x + 1} 8 and 7 are the two consecutive integers Their product is 56.
