What problem?

OpenStudy (anonymous):

Currently, Sam's coach is three times older than Sam. When Sam started soccer 15 years ago, his coach was six times his age. How old is Sam now?

not enough information??? i dont know haha.

OpenStudy (anonymous):

Two equations: C = 3S (currently) C-15 = 6(S-15) (fifteen years ago) Solve them.

OpenStudy (anonymous):

Substituting C = 3S into the second equation, you should get an equation in just S (for Sam's age). Then, you can solve it rather easily.
