See the solution process below:

#### Explanation:

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 $1$:

$\frac{5}{w} + \left(\frac{- 1}{-} 1 \times \frac{8}{-} w\right) \to$

$\frac{5}{w} + \left(\frac{- 1 \times 8}{- 1 \times - w}\right) \to$

$\frac{5}{w} + \frac{- 8}{w} \to$

$\frac{5}{w} - \frac{8}{w} \to$

$\frac{5 - 8}{w} \to$

$\frac{- 3}{w} \to$

$- \frac{3}{w}$
