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 $1$ :

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

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

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

$5/w - 8/w ->$

$(5 - 8)/w ->$

$(-3)/w ->$

$-3/w$
