Question 1150762
<br>
Of course there are many good ways to set up this problem for solving.<br>
Following is what I would do....<br>
Let x be Stephen's age 2 years ago; then Wendy's age then was 4x.<br>
The difference in their ages 2 years ago was then 4x-x = 3x.<br>
The difference in their ages (now, and 2 years ago, and always) is 69 years.<br>
So 2 years ago the difference in their ages was 3x = 69.<br>
So 2 years ago Stephen's age was x = 69/3 = 23 and Wendy's age was 4x = 92.<br>
So now Stephen's age is 23+2 = 25 years.<br>
