Linear Equations with Variables on Both Sides
 

Linear Equations with Variables on Both Sides problem 1


John was to celebrate his birthday. In the invitation he told his friends how old he will turn in a riddle.


"Today, my father is three times as old as I am". When I celebrate my birthday on Friday, I will be a year older, and my father will still be the same age. At that time, we will be 53 years old altogether."


What birthday will John be celebrating?
