I need help to answer the following problem: A group $G$ is said to be residually solvable if for every $g\in G \backslash \left\{e\right\}$ there is a normal subgroup $N$ of $G$ such that $g\notin N$ and $G/N$ is solvable. Show that a finite residually solvable group is solvable. Thanks in advance for your help.

By hypothesis, the obvious homomorphism of G into the direct product of all solvable factor groups of G is a monomorphism. Hence G is solvable.
