Ad libitum [116K]

Answer:

4-\frac{1}{2}m=20......No

\frac{1}{2}m+4=20.......Yes

\frac{1}{2}m-4=20.....No

4=20-\frac{1}{2}m......Yes

Step-by-step explanation:

Let the number of students in Byran's homeroom who have tickets to attend the school's musical be m.

Then 4 more than half this number is written as: \frac{1}{2}m+4

According to thee given statement, this expression is equal to 20.

\frac{1}{2}m+4=20

We can subtract \frac{1}{2}m from both sides to create an equivalent expression.

4=20-\frac{1}{2}m
