Consider the following equation with a parameter

a

.

\frac{2 x - a}{x - 5} = a

Choose the table that summarizes solutions of the equation according to the value of

a

.

\begin{array}{cc} Parameter & Solution set \\ a \in {2; 10} & \emptyset \\ a \in R ∖ {2; 10} & {\frac{4 a}{a - 2}} \end{array}

\begin{array}{cc} Parameter & Solution set \\ a = 5 & \emptyset \\ a \neq 5 & {\frac{4 a}{a - 2}} \end{array}

\begin{array}{cc} Parameter & Solution set \\ a = 2 & \emptyset \\ a \neq 5 & {\frac{4 a}{a - 2}} \end{array}
