A man and his three children spent $40 to attend a show. A second family of three children and their two parents spent $53 for the same show.
The system of linear equations shown represents this situation, where x is the cost of an adult ticket and y is the cost of a child ticket.
x+3y=40
2x+3y=53
How much will a family pay for 2 adult tickets and 4 child tickets?
