Hi and thanks for your reply =) A stupid mistake from my side, I changed it up and the only difference in the answer is that te^-t is now -te^-t. Still, the book doesn't agree with me unless they have the answer on some weird form. I also checked wolfram, they gave me this answer...

Hello! I'm stuck at the moment with this differential equation. I've been trying to use the method for solving these equations, but my answer is not correct according to my book. Could anyone please explain what I'm doing wrong? Thanks!

Alright, that made sense. Thanks for the help :)

So if h is 20 the solution would also be consistent?

Woops, I meant -20+h.

The thing is I don't know where to start. By multiplying with -4 and adding to second row, I have: 1 5 -4 0 20-h 0 And this doesn't really tell me anything, as I have never done matrix with variables before.
