Answer 1

It is actually 7. Just took the quiz so I can confirm this. ;D

Answer 2

1 = -(-w + 6)

First, simplify brackets. / Your problem should look like: 1 = w - 6
Second, add 6 to both sides. / Your problem should look like: 1 + 6 = w
Third, simplify 1 + 6 to 7. / Your problem should look like: 7 = w
Fourth, switch sides. / Your problem should look like: w = 7

Answer: w = 7 (C)
