Hi,
Vicki is eleven years older than Chuck.
Let chuck's age NOW be x and Vicki's age NOW be (x+11)
Five years from now, Vicki will be twice as old as Chuck
Find present ages:
(x+11 + 5) = 2(x+5)
6 = x chuck's age be NOW. and Vicki is 17 NOW
checking our work:
5 years from NOW ...
22 = 2(11) checks.
Wish You the Best in your Studies.
