You need to pick a variable for Peter's age.

Do you like x?

I can work with that.

Ok.
Let Peter's age = x
Peter's brother is 3 years older. Peter's brother is x + 3 years old.
Ok?

Okay, thankyou for taking ur time to draw that out lol

mathstudent55 · Answer

The total age is the sum of the three ages.
The ages are x, x + 3, and x + 26.
Add those ages up and set it equal to 38.
That is the equation you need to solve.
Since we let x = Peter's age, once you find x, you'll have your answer.
