**tchrwill**, Tuesday, September 21, 2010 at 10:20amAdam is 3 times as old as Cynthia or A = 3C.

Fred is 16 years younger than Adam or F = A - 16.

One year ago, Adam's age was twice the sum of Cynthia's and Fred's age or A - 1 = 2(C + F).

Find their present age.

Making the appropriate substitutions and solving yields C = 11, A = 33 and F = 17.
