Orion Elliott · Answer 1

Because theres a - on the outside, theres technically a - 1.

so distribute it and it becomes - x+7

So I think.

Helen Hanna · Answer 2

Another way to look at the problem is - 1 (-x-7). So you would do - 1 times - x which gives you positive x or 1x. Then take - 1 times - 7 which gives you 7.

So the answer is x+7.
