there are 266 students watching a play in the auditorium. there 10 rows with 20 students in each row and 5 rows with 8 students
kondor19780726 [428]
Let x = number of students in each of the remaining rows

266 = (10 x 20) + (5 x 8) + 2x
266 - (10 x 20) - (5 x 8) = 2x
266 - 200 - 40 = 2x
26 = 2x
x = 26/2
x = 13
