Jakathy is 32 years older than her nephew, Eric. Five years ago, her age was seventeen times as old as his. What is Jakathy's age?
------------
Equations:
j = e + 32
(j-5) = 17(e-5)
-----------------------
Substitute for "j" and solve for "e":
(e+32-5) = 17e-85
e+27 = 17e-85
16e = 112
e = 7 yrs old (erik's age now)
-----
Since j = e+32, j=39 yrs (Jakathy's age now)
