Alfonso is 6 years older than Brianna. In 5 years the sum of their ages will be 82. How old is Alfonso now

Answer 1

A = B+6

A+5 + B +5 = 82

A + B = 82 - 2(5) = 72

B+6 + B = 72

2B = 72-6 = 66

B= 66/2 = 33 years old for Brianna now

A = B+6 = 39 years old for Alphonso now

in five years they'll be 38 and 44 which sum to 82
