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.

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