C. 1/2m – 4 = 20

D. 4 = 20 – 1/2m

E. 20 + 1/2m = 4

Answer 1

Answer:

The option B and D are the equations.

Step-by-step explanation:

Let, the total number of students are x.

The number of students having the ticket is $4 + \frac{x}{2}$.

It is given that the number is 20.

Hence, $4 + \frac{x}{2} = 20\\4 = 20 - \frac{x}{2}$.

Option B is the equation.

Option D is also the same.

The difference is just, the variable is wriiten in the other side.
