Best ResponseYou've already chosen the best response.0Now he is twice sam's age. That is where the first equation came from. 10 years ago, so start with c  10 and s  10, the coach was 3 times sam's age. That is where the 3 comes from. I simplified then substituted in the 2s for c to solve for s. Then I knew c
