Students in grades 6, 7, and 8 sold a total of 320 concert tickets. Grade 6 students sold x tickets.
Grade 7 students sold s tickets and Grade 8 students sold t tickets.

Use the equation x + s + t = 320 to find x, the number of tickets that were sold by Grade 6 students.

x = 320 − t + s

x = 320 − t − s

x = 320 + t − s

x = s − t − 320
