Solve the following equation with unknown

x

and a real parameter

a \in R ∖ {- 1}

.

\frac{x}{a + 1} = x - a

\begin{array}{cc} Parameter & Solution set \\ a = 0 & R \\ a \notin {- 1; 0} & {a + 1} \end{array}

\begin{array}{cc} Parameter & Solution set \\ a = 0 & R \\ a \notin {- 1; 0} & \emptyset \end{array}

\begin{array}{cc} Parameter & Solution set \\ a = 0 & \emptyset \\ a \notin {- 1; 0} & {a + 1} \end{array}
