So it's been a really long time since I've done any ode/linear algebra and would like some help with this problem.
Derive the general solution of the given equation by using an appropriate change of variables
2[tex]\delta[/tex]u/[tex]\delta[/tex]t + 3[tex]\delta[/tex]u/[tex]\delta[/tex]x = 0
The thing that I'm really confused about is how do we decide what an appropriate change of variable is? Is there a general rule that I should go by?
The Attempt at a Solution
none yet because I'm not sure how to find the appropriate change of variable
