Question 937977
Steve is 5 times as old as Janis. In 12 years, he will be twice as old as she will be then. How old are they now?
 ---------------
Equations:
s = 5j
s+12 = 2(j+12)
---
Substitute for "s" and solve for "j":
5j + 12 = 2j + 24
3j = 12
j = 4 yrs (Janis's age now)
----
s = 5j = 20 yrs (Steve's age now)
