The problem of response of nonequilibrium systems is currently under intense investigation. We propose a general method of solution of the Liouville equation for thermostatted particle systems subjected to external forces which retains only the slow degrees of freedom, by projecting out the majority of fast variables. Response formulae, extending the Green-Kubo relations to dissipative dynamics, are provided, and comparison with numerical data is presented.
