Gaseous Equibrium Above a Reacting Solid

Solid NH2CONH4 is introduced into a flask containing iNH3 (g) at a partial pressure of 200 mm Hg. The temperature is 30°C. Kp for the decomposition of solid NH2CONH4
NH2CONH4 CO2 (g) + 2 NH3(g)
is Kp in (mm Hg)3. Calculate the total pressure at equilibrium. (NOTE, this may involve solving a cubic for the `real` root).
