Question 1150446: Corey is 58 years younger than Catherine. 9 years ago, Catherine's age was 3 times Corey's age. How old is Corey now Answer by ikleyn(52787) (Show Source):
Let Corey is x years old now.
Then Catherine's age is (x+58) years.
9 years ago . . .
(x+58)-9 = 3*(x-9)
Simplify and solve
x + 49 = 3x - 27
49 + 27 = 3x - x
76 = 2x
x = 76/2 = 38.
ANSWER. Corey now is 38 years old.
