Question

Kenneth is 10 years older than Andrew. Billy is 2 times as old as Andrew. Cameron is 8 years younger than Andrew. The combined age of the four is 77. How old is each boy?​

Answer 1

Kennet 25,Andrew 15,Billy 30,Cameron 7

Explanation:

Kenneth - 10+x,

Andrew - x,

Billy - 2x,

Cameron - x - 8,

10 + x + x + 2x + x - 8 =77

5x = 75

x = 15 (Andrew)

10+15= 25 (Kenneth)

2×15=30 (Billy)

15-8= 7 (Cameron)
