(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I will use d as a partial derivative symbol

du/dt-du/dx=0 use a change of variables to solve

3. The attempt at a solution

v=ax+bt w=cx+dt so then I use the chain rule

(du/dv)(dv/dx)+ (du/dv)(dv/dt)+(du/dw)(dw/dx)+(du/dw)(dw/dt)

ok then you are supposed to plug it back into the original equation but this is where i am confused do i plug in the partials with respect to t and then subtract the partials with respect x , please don’t use latex my computer wont bring up the images its old .
