night shift, and two more on the swing shift than on the night shift. How many are
The problem says
x + 3x + (x+2) = 102, where x is the number of the night employees.
From it,
5x = 102 - 2 = 100,
x = 100/5 = 20.
ANSWER. Night shift: 20 employees; day shift: 3*20 = 60 employees; swing shift: 20+2 = 22 employees.
