**Jai**, Saturday, May 14, 2011 at 11:28pmfirst observe that you are 24 years older than your son. also, since we are required of the ages, we represent these unknown ages using variables:

let x = your son's age

let x+24 = your age

note that when your son's age is x years, you are three times as old. therefore,

3x = x+24

3x-x = 24

2x = 24

x = 12 years old (age of your son)

and your age is

x+24 = 36 years old

checking: note that 12*3 = 36, which satisfies the condition given.

hope this helps~ :)
