Question

Are these two equal ?
Can we make -x/x+1 to x/-(x+1) and becomes x/-x-1​

Answer 1

Yes, they are equivalent.

One way you can check this is by substituting any number into x.

For example, x = 2:

• First equation :
`(-x)/(x + 1)`

⇒
`(-2)/(2 + 1)`

⇒
`(-2)/(3)`

• Second equation:
`(x)/(-x-1)`

⇒
`(2)/(-2-1)`

⇒
`(-2)/(3)`

As both forms of the equation give the same result after substitution, they are equivalent.
