See the solution process below:

To add fractions they must have a common denominator.

To get the second fraction over a common denominator with the first fraction we must multiply it by the appropriate form of #1#:

#5/w + ((-1)/-1 xx 8/-w) ->#

#5/w + ((-1 xx 8)/(-1 xx -w)) ->#

#5/w + (-8)/w ->#

#5/w - 8/w ->#

#(5 - 8)/w ->#

#(-3)/w ->#

#-3/w#
