The equations themselves consist of a pair of coupled, first-order, partial differential equations. The first equation shows that the induced voltage is related to the time rate-of-change of the current through the cable inductance, while the second shows, similarly, that the current drawn by the cable capacitance is related to the time rate-of ...

https://math.stackexchange.com/questions/306663
It is fairly straight forward to solve linear 1st order PDEs by the method of characteristics. For example, if ∂ t f + a ∂ x f = b f , we have that d f d t = b f on the characteristic curve of d x d t = a . From this we deduce that f ( t, x) = g ( C) e b t where x = a t + C . Now, how does this work when f is multidimensional.
