= 14 - 7w - w - 3

= (7 - 1)w - (14 - 3)

= __6w - 11__

Apparently the answer is actually; __17 - 2w__

However i don't see where i am going wrong! I think it might be something to do with a wider problem when it comes to simplifying expressions. Generally speaking i am fine when there are + operators in the equation, but the more - operators the more difficulty I have.

Can someone point me in the right direction?

Thanks.
