Step 1.1

Factor $- 1$ out of $- 3 (y + 4)$ .

$- (3 (y + 4)) - 4 (4 y - 8) - 10 y$

Step 1.2

Factor $- 1$ out of $- 4 (4 y - 8)$ .

$- (3 (y + 4)) - (4 (4 y - 8)) - 10 y$

Step 1.3

Factor $- 1$ out of $- 10 y$ .

$- (3 (y + 4)) - (4 (4 y - 8)) - (10 y)$

Step 1.4

Factor $- 1$ out of $- (3 (y + 4)) - (4 (4 y - 8))$ .

$- (3 (y + 4) + 4 (4 y - 8)) - (10 y)$

Step 1.5

Factor $- 1$ out of $- (3 (y + 4) + 4 (4 y - 8)) - (10 y)$ .

$- (3 (y + 4) + 4 (4 y - 8) + 10 y)$

Step 2

Apply the distributive property.

$- (3 y + 3 \cdot 4 + 4 (4 y - 8) + 10 y)$

Step 3

Multiply $3$ by $4$ .

$- (3 y + 12 + 4 (4 y - 8) + 10 y)$

Step 4

Apply the distributive property.

$- (3 y + 12 + 4 (4 y) + 4 \cdot - 8 + 10 y)$

Step 5

Multiply $4$ by $4$ .

$- (3 y + 12 + 16 y + 4 \cdot - 8 + 10 y)$

Step 6

Multiply $4$ by $- 8$ .

$- (3 y + 12 + 16 y - 32 + 10 y)$

Step 7

Add $3 y$ and $16 y$ .

$- (19 y + 12 - 32 + 10 y)$

Step 8

Add $19 y$ and $10 y$ .

$- (29 y + 12 - 32)$

Step 9

Subtract $32$ from $12$ .

$- (29 y - 20)$
