You can put this solution on YOUR website! Let's say Charlie is c, Diane is d, Paco is p, and Brett is b. Now plug what you know for each value: c=b+15; d=46; p=d-10; p=b+33.
First solve for Paco's age (p=d-10), where d=46: (p=46-10) = p=36.
Now use Paco's age to solve for Brett's age (p=b+33), where p=36
(36=b+33) = b=3.
Now use Brett's age to find Charlie's age: (c=b+15), where b=3
(c=3+15) = c=18
Charlie is 18 years old.
