Question 859636
Three years ago Elaine was five times as old as Jerry. Today she is three times as old as Jerry. How old are Jerry and Elaine today?
----------
Equations:
e-3 = 5(j-3)
e = 3j
--------
Substitute for "e" and solve for "j":
3j-3 = 5j-15
2j = 12
Jerry = 6 yrs (Jerry[s age now)
-----------------------------------------
Solve for "e":
e = 3j = 18 yrs (Elaine's age now)
