$- \frac{1}{2} (32 x - 40) + (20 x - 4)$

Step 1

Remove parentheses.

$- \frac{1}{2} \cdot (32 x - 40) + 20 x - 4$

Step 2

Factor $\frac{1}{2}$ out of each term.

$\frac{1}{2} \cdot (- 1 (32 x - 40) + 40 x - 8)$

Step 3

Apply the distributive property.

$\frac{1}{2} \cdot (- 1 (32 x) - 1 \cdot - 40 + 40 x - 8)$

Step 4

Multiply $32$ by $- 1$ .

$\frac{1}{2} \cdot (- 32 x - 1 \cdot - 40 + 40 x - 8)$

Step 5

Multiply $- 1$ by $- 40$ .

$\frac{1}{2} \cdot (- 32 x + 40 + 40 x - 8)$

Step 6

Add $- 32 x$ and $40 x$ .

$\frac{1}{2} \cdot (8 x + 40 - 8)$

Step 7

Subtract $8$ from $40$ .

$\frac{1}{2} \cdot (8 x + 32)$
