A man was 27 years older than his son ten years ago.His wife is 4 years younger than he is.if their total age is 116 years now ,how old is the son?

M - 27 = S

M - 4 = W

M + W + S = 116

Substitute M-27 and M-4 for S and W respectively in the third equation and solve for M. Insert that value into the first equation to solve for S.
