Linear Differential Equation Help

  • #1
This is a question I have been staring at for a while now. I can't figure it out for the life of me.

'Solve the following equation that is linear in x: y + (3 + 3x - y)dy/dx = 0

I don't even know where to start. Any help would be greatly appreciated.

The equation becomes exact if you multiply both sides by the integrating factor μ = y2.

You can then find the solution using regular methods for solving exact equations.

Not sure if Wikipedia explains the method very well, but just so you have an idea of what I'm talking about :)
