A theater charges $5 for student tickets and $7 for adult tickets. They sold 75 tickets for a total of $425. Which set of equations can be used to determine x, the number of student tickets sold, and y, the number of adult tickets sold?

•  x – y = 75 
  5x + 7y = 425
•  x – y = 425 
   5x + 7y = 75
•  x + y = 75 
  5x + 7y = 425
• x + y = 425 
  5x + 7y = 75
