Twenty, which is 4 more than half, of the students in Bryan’s homeroom have tickets to attend the school’s musical. Choose Yes or No to tell whether each of the following equations can be used to find the number of students in Bryan’s homeroom.

Answer :

One possible equation would be 20 = 1/2x + 4.

Let x be the number of students in his homeroom.  1/2x is half of the students in his homeroom.  Four more than 1/2 would be 1/2x + 4.  This is, or equals, the 20 students that have tickets.

Answer:

No 4 - 1/2 = 20

Yes 1/2m + 4 = 20

No 1/2m - 4 = 20

Yes 4 = 20 - 1/2m
