**Reiny**, Monday, January 20, 2014 at 12:11am10 years ago:

son --- x

father --- 3x

NOW:

son --- x+10

father --- 3x+10

12 years from now:

son --- x+22

father -- 3x + 22

x+22 = (3/5)(3x + 22)

times 5

5x + 110 = 9x + 66

-4x = -44

x = 11

so 5 years ago:

son = present age - 5

= (11+10) - 5 = 16

father = 3x+10 - 5 = 38

So 5 years ago, the son was 16, and the father was 38

(right now the son is 21, and the father is 43)
