Question 519048
Find two consecutive even numbers whose sum is 22. 


x = 1st consecutive even number
x + 2 = 2nd consecutive even number


x + x + 2 = 22 {their sum is 22}
2x + 2 = 22 {combined like terms}
2x = 20 {subtracted 2 from both sides}
x = 10 {divided both sides by 2}
x + 2 = 12 {substituted 10, in for x, into x + 2}


10 and 12 are the two consecutive even numbers
