Answer 3

wat do you think

Answer 4

its the 3rd one the 17 is positive in that one

Answer 5

already been answered ahsome stop trying to steal my street cred

Answer 6

Lets do them one by one. Lets leave the first one the same, and see if the other three are similar:
First equation: \(x-17\)

The second one is: \(x+(-17)\)

When you add a negative number, its the same is minusing the number. Here is an example
\(x+(-y)=x-y\)
So, \(x+(-17)\) is the same as \(x-17\). That is the same as the first one, so its OK

The third one is: \(x-(-17\)
When you minus a negative number, its the same is adding the number. Here is an example
\(x-(-y)=x+y\)

So, \(x-(-17)\) is the same as \(x+17\). This is not the same as the first one, and therefore is the culprit

That would be the steps, @peterg2001
