Hello Kiddo. 

This question is a bit confusing to me, but I think I grasped the concept. 
1. x best represents Sarah's mom's age. 
2. x - 24 best represents Sarah's mom's age minus how much younger Sarah is than her mom. 
3. The expression would look a little like this:
2x-24 = 68
    + 24  +24
2x = 92 
/2     /2
x = 46.

Which means, Sarah is 22 and her mom is 46 years of age. 
If you need more clarification, I'd be more than happy to elaborate further.
