Answer:
[tex]4 + \dfrac{x}{2} = 20[/tex]
where x is the number of students in Bryan’s homeroom.
Step-by-step explanation:
We are given the following in the question:
Let x be the number of students in Bryan’s homeroom.
Number of students having tickets = 20
Then according to the question:
[tex]4 + \dfrac{x}{2} = 20[/tex]
Solving the above equation, we have,
[tex]4 + \dfrac{x}{2} = 20\\\\8 + x = 40\\x = 40-8\\x = 32[/tex]
Thus, there are 32 students in Bryan’s homeroom.
