.

64 + x = 3*(18+x), where x is the value under the question. 64 + x = 54 + 3x 64 - 54 = 3x - x 10 = 2x ====> x = 10/2 = 5 years. Answer. In 5 years. Check. In 5 years they will be 69 and 23 years old. 69 = 23*3. ! Correct !

When Ashley is 3 times as old as Stephanie, their ages can be represented as 3x and x; the difference in their ages will be 2x.

The difference in their ages is now, and always will be, 46 years.

2x = 46 --> x = 23; so Ashley will be 3 times as old as Stephanie when Stephanie is 23 and Ashley is 69.

Since Ashley is now 64, that will be 5 years from now.
