    The only way that can be true is if all factors are positive or 2 are negative and 1 positive.

    \[\huge -\frac{6}{x+1} > \frac{1}{x}\] \[\huge -6x>x+1\] \[\huge 7x<-1\] \[\huge x<-\frac{1}{7}\]

    You can't do that @Azteck You don't know if x is positive or negative thus you don't know whether to flip the inequality symbol or not. The way I showed is the way to handle it.
