Question 1165112
--------------------------------------------------
Adam is twice as old as Bill, and Bill is 12 years younger than Charles. In 5
years, Charles will be twice as old as Bill. How old are each of the brothers?
-------------------------------------------------

<pre>
PERSON            AGE
Adam              2(z-12)
Bill              z-12
Charles            z
</pre>
The second sentence:
{{{z+5=2((z-12)+5)}}}
Solve this and you can evaluate the other two brothers' ages.
