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?

asked by Jan
  1. M = 2y

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

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

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