I am working on this problem. I am trying to set it up correctly. Adult tickets to a play cost $13 and child tickets cost $10. If there were 22 people at a performance and the theater collected $277 from ticket sales, how many adults and how many children attended the play. First, x= Adult y = child x+y=22 13x + 10y=22 I am not certain if I should multiply the second equation by -10 so that I can use the addtion method. What is the best way to solve this problem?
