Question

two years ago jenny was four times as old as helen. six years from now jenny will be twice as old as helen. how old are the girls now

Answer 1

Let Jenny's age (today) be J and Helen's age (today) be H We have the following equations: J-2 = (H-2)4J+6 = (H+6)2 Simplify J-2 = 4H-8J+6 = 2H+12 J=4H-6J=2H+6 Solve the system of equations by elimination -J=-4H+62J=4H+12 J=18 → plug into original equation → 18=4H-6 → 24=4H → H=6 We can check to verify if needed, but we will get that Jenny is 18 and Helen is 6
