Question from Sabrina, a student:

Amy is 2 years younger than Brian.
The total of their ages is 26 years.

Hi Sabrina,

If Brian is 12 years old how old is Peter? How did you get that number? How old is Amy? How did you get that number.

If Brian is x years old how old is Peter? How old is Amy? What is the sum of their ages? Solve for x.
