Step 1.1

Factor $9$ out of $- 9 z$ .

$\frac{9 (- z) - 9 y}{z + y}$

Step 1.2

Factor $9$ out of $- 9 y$ .

$\frac{9 (- z) + 9 (- y)}{z + y}$

Step 1.3

Factor $9$ out of $9 (- z) + 9 (- y)$ .

$\frac{9 (- z - y)}{z + y}$

$\frac{9 (- z - y)}{z + y}$

Step 2

Cancel the common factor of $- z - y$ and $z + y$ .

Step 2.1

Factor $- 1$ out of $- z$ .

$\frac{9 (- (z) - y)}{z + y}$

Step 2.2

Factor $- 1$ out of $- y$ .

$\frac{9 (- (z) - (y))}{z + y}$

Step 2.3

Factor $- 1$ out of $- (z) - (y)$ .

$\frac{9 (- (z + y))}{z + y}$

Step 2.4

Rewrite $- (z + y)$ as $- 1 (z + y)$ .

$\frac{9 (- 1 (z + y))}{z + y}$

Step 2.5

Cancel the common factor.

$\frac{9 (- 1 (z + y))}{z + y}$

Step 2.6

Divide $9 \cdot (- 1)$ by $1$ .

$9 \cdot (- 1)$

$9 \cdot (- 1)$

Step 3

Multiply $9$ by $- 1$ .

$- 9$
