Question

Adult tickets to a concert cost $15 and student tickets cost $12. A total of 300 tickets are sold, and the total receipts were $4140. Write and solve a system of equations to find how many student tickets were sold.
a+c = 300
15a+12c = 4140
Now work your magic.
Which variables are x and y like I need to know if a is x or c is y

??? !!!
there is no x and y
a = adult
c = child
you don't always need x and y to solve equations.
