Homomorphic image of a free group Given a group $G$ with a generating set $S$, such that $|S|=n$, I need to prove that $G$ is a homomorphic image of $F_n$. 
Right now I'm just looking for any tips for how to even start this proof or how to start thinking about the question. 

Let $a_1,\dots a_n$ be generators for $F_n$, and $g_1,\dots g_n$ generators for $G$. Note that a homomorphism from $F_n$ is given by the images of $a_i$. So let's take the homomorphism given by $a_i\mapsto g_i$. Any element in $G$ can be written as product of $g_i$-s. Then the product of corresponding $a_i$-s will be in the preimage of our element.
ADDITIONAL: you can study the kernel of the map. What do elements in the kernel represent?
