Answer:
Yes, they are equivalent.
One way you can check this is by substituting any number into x.
For example, x = 2:
• First equation : [tex]\frac{-x}{x + 1}[/tex]
⇒ [tex]\frac{-2}{2 + 1}[/tex]
⇒ [tex]\frac{-2}{3}[/tex]
• Second equation: [tex]\frac{x}{-x-1}[/tex]
⇒ [tex]\frac{2}{-2-1}[/tex]
⇒ [tex]\frac{-2}{3}[/tex]
As both forms of the equation give the same result after substitution, they are equivalent.
