Jim is three times as old as his son. In 10 years, Jim will be twice as old as his
son. What are their current ages?
~~~~~~~~~~~~~~ 

The son's age = x years.

The Jim's age= 3x years.


In 10 years

    2(x+10) = 3x+10


Simplify and find x

    2x + 20 = 3x + 10

    20 - 10 = 3x - 2x

      10    =    x.


ANSWER.  The son is 10 years old.  Jim is 3*10 = 30 years old.

Solved.
