The equation that can be used to find the number of students performing in the play is x = (550 - 370) / 12
Given:
Total seats in the auditorium = 550
Tickets remaining = 370
Tickets sold by each performing student = 12
Total seats = Total number of tickets
let
number of students performing = x
Number of students performing = (Total seats in the auditorium - Tickets remaining) / Tickets sold by each performing student
x = (550 - 370) / 12
= 180 / 12
x = 15
Therefore, the number of students performing in the play is 15 students.
