Question 631779
Gerry is twice Julia's age.Ten years ago,the square of Julia's age was 14 more than Gerry's age.What is the present age of Gerry?
-------
Equations:
G = 2J
(J-10)^2 = (G-10)+14
----
Substitute and solve for "J":
(J-10)^2 = (2J-10) + 14
J^2 - 20J + 100 = 2J + 4
J^2 - 22 J + 96 = 0
J = 16 
---
Solve for G:
G = 2J = 32 (Gerry's age now)

------------
