You can put this solution on YOUR website! It is easy, just write the problem in slightly more mathematical manner:
father's age = 13 * son's age
son's age + 10 = (father's age + 10 )/3
Because we know that father's age is 13* son's age, we have
son's age + 10 = (13*son's age + 10)/3
or
3*(son's age + 10) = (13*son's age + 10)
or
3*son's age + 30 = 13*son's age + 10
20 = 10 * son's age
ANSWER:
son's age = 2
father's age = 13*2 = 26.
