<U>ANSWER</U>.  John is 22 years old;  Mai is 10 years old.



<U>Solution</U>


<pre>
For a minute, take off 2 years from the John's age.


Then you have two quantities:  the "corrected" John's age and the Mia's age.


The first quantity is 2 times the second and they sum up to 32-2 = 30.


x + 2x = 30  ====>  3x = 30  ====>  x = 30/3 = 10.


Thus Mia is 10 years old and John is 2x + 2 = 2*10 + 2 = 22 years old.
</pre>

Solved.
