Identify the optimal first step to solve the following equation. The operation is intended to be used on both sides of the equation.

\frac{2 x + 1}{x - 1} + \frac{x + 1}{x - 1} = \frac{11}{2}

multiply by

2 (x - 1)

, assuming

x \neq 1

multiply by

(2 x + 1)

, assuming

x \neq - \frac{1}{2}

multiply by

(x + 1)

, assuming

x \neq - 1

multiply by

\frac{1}{2 x + 1}

, assuming

x \neq - \frac{1}{2}

multiply by

\frac{1}{x + 1}

, assuming

x \neq - 1

multiply by

2 (2 x + 1) (x + 1)

, assuming

x \neq - \frac{1}{2}

and

x \neq - 1
