well 68-24 is 44 so 22 is half of that, so if one is 22 and the other is 46 (22+24) than they add up to 68. 

x best represents mother's age.

x - 24 best represents Sarah's age.

Age of Sarah is 22

Step-by-step explanation:

x best represents mother's age.

x - 24 best represents Sarah's age.

Sum of their ages is 68

That is

                 x + x -24 = 68

                2x = 68 + 24

                 2x = 92

                    x = 46

Sarah's age = x -24 = 46 -24 = 22

x best represents mother's age.

x - 24 best represents Sarah's age.

Age of Sarah is 22
