Question 1125337: Juan is 90 years younger than Stacy. 2 years ago, Stacy's age was 4 times Juan's age. How old is Juan now? Answer by ikleyn(52787) (Show Source):
Let J be the Juan'a age.
Then the Stacy age is (J+90), according to the condition.
2 years ago:
(J+90)-2 = 4*(J-2)
J + 88 = 4J - 8
88 + 8 = 4J - J
96 = 3J ====> J = 96/3 = 32.
Answer. Juan is 32 years old now.
