Mr B is now twice as old as his younger brother. Eight years ago he was three times as old as his younger brother was then. How old is the younger brother now?

1. PsyDAG

M = 2y

(M-8) = 3(y-8)

Substitute 2y for M in the second equation and solve for y.

2. Anonymous

2y-8=3y-24
24-8=3y-2y
16=y
Therefore Younger brother is 16 years
