I could really use an easy answer, I can't find any I understand. I need to use a linear system of equations to answer.

The school that Kevin goes to is selling tickets to a field trip. On the first day of ticket sales, the school sold 3 adult tickets and 1 child ticket for a total of $38. The school took in $52 on the second day by selling 3 adult tickets and 2 child tickets. Find the price of an adult ticket and the price of a child ticket.
