Answer:

w = 1

Explanation:

2(4 - 2w) - 8 = -4

(2*4 + 2*-2w) - 8 = -4

(8 - 4w) - 8 = -4

-4w + 8 - 8 = -4

-4w = -4

w = -4/-4

w = 1

Check:

2(4 - 2*1) - 8 = -4

2(4-2) -8 = -4

2(2) - 8 = -4

4 - 8 = -4

2(4 − 2w) - 8 = -4

Use the distributive property to multiply 2 times 4−2w.

8 - 4w - 8 = -4

Subtract 8 from 8 to get 0.

-4w = -4

Divide both sides by −4.

w = -4/-4

Divide −4 by −4 to get 1.

w = 1
