Deriving the equation for lines of constant enthalpy

How would one derive the equation for (dP/dV)H? That is the partial of P over the partial of V, holding H constant. I've tried many different things, triple product rule, maxwell relationships, and nothing seems to work. I appreciate any advice.

[tex]dT=(\frac{\partial T}{\partial P})_VdP+(\frac{\partial T}{\partial V})_PdV[/tex] You need to combine this with the equation: [tex]dH=C_PdT+(VT(\frac{\partial V}{\partial T})_P)dP[/tex]
