**Henry**, Saturday, January 26, 2013 at 3:46pmX Yrs old = Age of one son.

3x yrs old = Age of other son.

4(x+3x) = 16x = Age of the father.

(x+24) + (3x+24) = (16x+24) - 12.

4x + 48 = 16x + 12

4x - 16x = 12 - 48

-12x = -36

X = 3

x+24 = 3+24 = 27 Yrs=Youngest son's age,

3x+24 = 9+24 = 33 Yrs=Oldest son's age.

16x+24 = 48+24=72 Yrs=The father's age.
