You can put this solution on YOUR website! 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)
