**drwls**, Wednesday, March 17, 2010 at 11:18amYou got the right answer without using equations. Here is the way to do it with algebra. Let x be the younger person's age now, and y be the older person's age now.

y = 3x

(y + 15) = 2(x + 15)

Now eliminate one variable using algebra.

y = 2x +30 -15 = 2x + 15

3x = 2x + 15

x = 15.
