solve using two equations with two variables.
High school Musical El Segundo High School put on their annual musical.The students sold 650 tickets for a value of $4375.00. If orchestra seats cost $7.50 and balcony seats costs $3.50, how many of each kind of seats were sold? This question is from textbook Toby Slater beginning Algebra

Assign variables to things you don't know. Then write expressions based on the information given in the problem.
Let x = orchestra seat tickets sold
and y = balcony seat tickets sold
From:"The students sold 650 tickets" we get:
x + y = 650 <<--equation #1
Then, since the problem states the total in-take and costs of each ticket we get:
7.50x + 3.50y = 4375 <<--equation #2

Now you have two equations and two unknowns:
x + y = 650
7.50x + 3.50y = 4375
Solve the above with your favorite method (i.e., substitution method, cramer's rule, etc)
