Answer:

[tex]4-\frac{1}{2}m=20[/tex]......No

[tex]\frac{1}{2}m+4=20[/tex].......Yes

[tex]\frac{1}{2}m-4=20[/tex].....No

[tex]4=20-\frac{1}{2}m[/tex]......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: [tex]\frac{1}{2}m+4[/tex]

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

[tex]\frac{1}{2}m+4=20[/tex]

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

[tex]4=20-\frac{1}{2}m[/tex]
