Question

If the sum of two consecutive even integers is 20 find the numbers

Answer 1

"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
