WebAdd a comment. 1. Another approach consists in adding the two ODEs : d y + d x d t = x + y + 2 e t = d u d t = u + 2 e t where u = y + x. This first order linear ODE is easy to solve : u = 2 t e t + c 1 e t → y = − x + 2 t e t + c 1 e t. Puting it into the first ODE : d x d t = 3 x − 2 t e t − c 1 e t.
