You would solve the complementary function, that is, y'' + y' + y = 0, then you would take a particular integral in the same form as the one on the right hand side of the equation - so in this case, \lambda e^x.

To find that particular integral, substitute back into the original equation to find what \lambda, then the particular solution to the whole thing would be the solution to y'' + y' + y = 0 plus whatever you found for \lambda e^x.
