I need help how to start & solve this problem. The question has to revolve around seperate equations turning into matrix(ces)


Robin has save 177 Dollars for her MP3 Player. he has 51 bills which consists of $1's,#5's and $10's bills.
If the number of $5 bills is three times the number of $10 bills, how many of each does Robin have?

Thanks for your help!
