Question 930071: one brother is 5 years older than the other. the sum of thier ages is 27. what are thier ages?
Answer by algebrahouse.com(1659)   (Show Source):
You can put this solution on YOUR website! x = one brother
x + 5 = other brother
x + x + 5 = 27 {the sum of their ages is 27
2x + 5 = 27 {combined like terms}
2x = 22 {subtracted 5 from each side}
x = 11 {divided each side by 2}
x + 5 = 16 {substituted 5, in for x, into x + 5}
one brother is 11
the other brother is 16
