Question 536249: the sum of two consecutive odd numbers is 20. find the numbers.

You can put this solution on YOUR website! "the sum of two consecutive odd numbers is 20. find the numbers."
x = 1st odd integer
x + 2 = 2nd odd integer
x + x + 2 = 20 {the sum of the two is 20}
2x + 2 = 20 {combined like terms}
2x = 18 {subtracted 2 from both sides}
x = 9 {divided both sides by 2}
x + 2 = 11 {substituted 9, in for x, into x + 2}
9 and 11 are the two consecutive odd integers
