Exact analytic solutions to the linearized Boltzmann equation for combined electron-electron electron-impurity scattering have been obtained. For the usual two-band model of a transition metal, these make possible a precise theoretical consideration of the experimentally important question as to the additivity of the two scattering mechanisms.
