Question 1164417
<br>
The difference in their ages is 10 years; 8 years ago, Faith's age was 3 times Grace's age.<br>
Let x be Grace's age 8 years ago; then Faith's age 8 years ago was 3x.  The difference in their ages then was 3x-x = 2x.<br>
But the difference in their ages then was 10 years.  So 2x=10, and x=5.<br>
That means their ages 8 years ago were x=5 and 3x=15.<br>
And that means their current ages are 13 and 23.<br>
