 
I am going to use one letter, $C$ to stand for Caleb's age today and another letter, $J$ to stand for Juliet's age today. Sine the sum of their ages is 25 years you know that \[C + J = 25.\] This is the first equation. What was Caleb's age 8 years ago? What was Juliet's age 8 years ago? At this time Caleb's age was twice Juliet's age. This gives you a second equation. Solve the two equations for $C$ and $J.$ Make sure you verify your answer,
