Identify the optimal first step to solve the following equation. The operation is intended to be used on both sides of the equation. \[ \frac{2x + 1} {x - 1} + \frac{x + 1} {x - 1} = \frac{11} {2} \]
multiply by \(2(x - 1)\), assuming \(x\neq 1\)
multiply by \((2x + 1)\), assuming \(x\neq -\frac{1} {2}\)
multiply by \((x + 1)\), assuming \(x\neq - 1\)
multiply by \(\frac{1} {2x+1}\), assuming \(x\neq -\frac{1} {2}\)
multiply by \(\frac{1} {x+1}\), assuming \(x\neq - 1\)
multiply by \(2(2x + 1)(x + 1)\), assuming \(x\neq -\frac{1} {2}\) and \(x\neq - 1\)
