Question 930071
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
