Question 513455
john is older than his cousin bill. 
j > b
-------------------
bill's age is 3 years more than one half the age of john.
b = (1/2)j + 3
------

if the difference in their ages is less than four years
j - b < 4
-------------------

What is the oldest that john can be in whole number of years?
---
Substitute for "b" and solve for "j":
j - [(j/2)+3] < 4
(1/2)j -3 < 4
(1/2)j < 7
j < 14 yrs (John is less than 14 so the oldest John can be is 13).
