#(x-w+1)/2#

To subtract fractions, make sure that both fractions have the same denominator.

Same denominators:

#2/3, 14/3#

#-8/11, 19/11#

Not the same denominators:

#1/4, 2/7#

#-13/17, 89/64#

These two fractions both have the denominator of 2.

To subtract, simply subtract the numerator of the second fraction from the first:

#(x+1-w)/2#

#(x-w+1)/2#
