Step 1.1

Apply the distributive property.

$z y + z \cdot 4 - 7 (y + 4)$

Step 1.2

Move $4$ to the left of $z$ .

$z y + 4 \cdot z - 7 (y + 4)$

Step 1.3

Apply the distributive property.

$z y + 4 z - 7 y - 7 \cdot 4$

Step 1.4

Multiply $- 7$ by $4$ .

$z y + 4 z - 7 y - 28$

$z y + 4 z - 7 y - 28$
