this is the question:
so i set:
dy/dx + y = e^3x
but im not sure where to go from here.
I could also do
dy + y dx = e^3x dx
Can someone please explain what i should do?

Find an integrating factor
Do you know why?
What do you get?
right right. So i get e^x as the integrating factor. I think i should know what to do now
Multiply it through both sides of the equation, what do you get?
