Question 536249
"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
