   The problem goes like this:
   
   "Show that [itex]x = \sin(2t) + e^t, y = 2\cos(2t) - 4e^t[/itex] is a solution of
   [tex]x' = 5e^t + y, y' = -4x [/tex]
   and find a family of solutions of this system.
   
   I already did the 'showing' part. I am having trouble finding the general solution for this system. Can someone help me?

   Have you looked at the second derivative of x?
