LINEAR EQUATIONS!!!!!

[ilianaaloha]

can someone help me with this linear equation word problem? solve using two equations with two variables each.

El Segundo High School is putting on their annual musical. The students sold 650 tickets for a total of $4375. If orchestra seats cost $7.50 and balcony seats cost $3.50, how many of each were sold?

 

[skeeter]

let x = number of orchestra seats
y = number of balcony seats

x + y = 650

(7.50)x + (3.50)y = 4375

solve the system
