Question 1166632
.
Adam is 20 years younger than Brian. In two years Brian will be twice as old as Adam. How old are they now?
~~~~~~~~~~~~~~~~~



<pre>
Let A be the Adam's age.

Then the Brian's age is (A + 20)  years.



In two years  Adam's age will be  (A+2);  Brian's age will be (A+22) years,

and you have this equation

    A + 22 = 2*(A+2).


Simplify and find A

    A + 22 = 2A + 4

    22 - 4 = 2A - A

     A     = 18.


<U>ANSWER</U>.  A is 18 years old.  B is 18+20 = 38 years old.


<U>CHECK</U>.  In 2 years, they will be  20 and 40 years old.   The ratio is 2.  ! Correct !
</pre>

Solved.
