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.

then what we have here is a sentence that has not been proofread
for errors, and doesn't ask any question. I'm not going to worry about it.

Or if you're not as strong with mental math, plug into a calculator 180 times the decimal version of 50% which is .5. 180 times .5 equals 90.
