7.14.1.5 Some doubts about symbolic equations in Wolfram Mathematica

https://mathematica.stackexchange.com/landing/r/digest?cta=question&id=244961

I need to perform the following operations using Wolfram Mathematica. 
I have these equations: 
$$a b = c+d+e$$ 
$$\frac{d}{f}=g h + i$$ 
$$k=\frac{a}{c}$$ 
I need to obtain $k$ as a function of: $a,b,c,e,...
