Solve the following equation with unknown \(x\) and a real parameter \(a\in\mathbb{R}\setminus\{-1\}\).
\[\frac{x} {a+1} = x - a\]
\(\begin{array}{cc} \hline \text{Parameter} & \text{Solution set}\\ \hline
a=0 & \mathbb{R} \\
a\notin\{-1;0\} & \{a+1\}
\\\hline \end{array}\)

a=0 & \mathbb{R} \\
a\notin\{-1;0\} & \emptyset
