The age of Lucy is half the age of Annie. Ten years from now, Annie will be 5 more than the age of Annie. How?
Somebody help me to answer this question?

This is entirely possible with the help of a little algebra.
First, let Lucy's present age be x.
Annie's present age is 2x.
After 10 years: Annie's age becomes 2x+10, Lucy's x+10
We know that the difference of their ages is 5, and that Annie is older, so:
2x+10 - (x+10) = 5
x = 5
By substituting: Lucy's present age is 5. Annie's is 10.
After 10 years, Lucy will be 15. Annie will be 20.
