$\begin{align}\frac{x-1}{x+1}&\ \textless \ 1 \\ \frac{x-1}{x+1}-1&\ \textless \ 0 \\ \frac{x-1}{x+1}-\frac{x+1}{x+1}&\ \textless \ 0 \\ \frac{x-1-(x+1)}{x+1}&\ \textless \ 0 \\ -\frac{2}{x+1}&\ \textless \ 0 \\ \frac1{x+1}&\ \textgreater \ 0&\boxed{?}\end{align}
Karena x + 1 akan positif apabila x > -1
Maka,
HP = {x | x > -1, x E R}

Note:
\boxed{?} = Kedua ruas dibagi (-2), tanda juga dibalik karena negatif.
