9 yrs. ago:
Valerie's age = X yrs.
Jose' age = 3x yrs.
The present:
Valerie: (x+9) yrs. old.
Jose: (3x+9) yrs. old.
x+9 + 3x+9 = 78.
4x + 18 = 78.
4x = 60.
X = 15 yrs.
3x+9 = 3*15 + 9 = 54 yrs. = Jose's age.
The sum of the ages of Jose and Valerie is 78 years. 9 years ago, Jose's age was 3 times Valerie's age. How old is Jose now?
