Question 937702
Lucy is k years old
 How old was she three years ago:: k-3
---------------------------------- 
How old will she be in four years time:: k + 4
----------------------------------
 Find her age if half of what she was three year ago is equal to one third of what she will be in four year time
Equation:
(1/2)(k-3) = (1/3)(k+4)
--------
3(k-3) = 2(k+4)
3k-9 = 2k+8
k = 17 (Lucy's age now)
