Help with PDE (first partial derivatives)

    1. The problem statement, all variables and given/known data

    I would like to know how to solve the PDE

    [tex] \frac{\partial f}{\partial x}+\frac{\partial f}{\partial y}+\frac{\partial f}{\partial z}=g(x,y,z) [/tex]

    * f is the unknown function * g(x,y,z) is a known and smooth function

    2. Relevant equations

    [tex] divf=g [/tex]

    3. The attempt at a solution

    - I have tried using 'Divergence theorem' but got no further info abut f.

    - If g(x,y,z)= g(x)+g(y)+g(z) i can provide a solution othewise i have no
    idea ..
