Answer:
x = 28
Step-by-step explanation:
Let the total number of students = x
x/7 + 3x/7 + 2x/7 + 4 = x If that is all there is. If it isn't the problem can't be done. Combine like terms.
x(1 + 3 + 2)/7 + 4 = x
x (6/7) + 4 = x Subtract 6x/7 from both sides
4 = x - 6x/7
4 = 7x/7 - 6x/7 Combine
4 = 1/7x Multiply both sides by 7
4*7 = 7x / 7
x = 28
