First, distribute the minus sign across the second set. So you have:

x - y + 1 - x - y + 1

Now, we combine like terms:
x-x=0
-y-y=-2y
1+1=2

So we have -2y+2

Hope that helps.

The fraction indicating the number of students who are not wearing either blue or white shirt is:

There are 6 students who are not wearing either a blue or a white shirt.

Hope this helps~
