Identify the optimal first step to solve the following equation. The operation is intended to be used on both sides of the equation. 4+xx+1=x−3x+2
multiply by (x+2)⋅(x+1), assuming x≠−2 and x≠−1
multiply by (4+x)⋅(x−3), assuming x≠−4 and x≠3
multiply by (4+x)⋅(x+1), assuming x≠−4 and x≠−1
multiply by (x−3)⋅(x+2), assuming x≠3 and x≠−2
multiply by (x−3), assuming x≠3
multiply by (4+x), assuming x≠−4
