Identify the optimal first step to solve the following equation. The operation is intended to be used on both sides of the equation. \[ \frac{4 + x} {x + 1} = \frac{x - 3} {x + 2} \]
multiply by \((x + 2)\cdot (x + 1)\), assuming \(x\neq - 2\) and \(x\neq - 1\)
multiply by \((4 + x)\cdot (x - 3)\), assuming \(x\neq - 4\) and \(x\neq 3\)
multiply by \((4 + x)\cdot (x + 1)\), assuming \(x\neq - 4\) and \(x\neq - 1\)
multiply by \((x - 3)\cdot (x + 2)\), assuming \(x\neq 3\) and \(x\neq - 2\)
multiply by \((x - 3)\), assuming \(x\neq 3\)
multiply by \((4 + x)\), assuming \(x\neq - 4\)
