Problem:

Find a partial differential equation whose characteristic curves are the lines x-y=a, x+2y=b where a,b are arbitrary real constants.

Solution:

Since the partial differential equation (PDE) admits real characteristics, then it will be of hyperbolic type, that is:
( 1)
According to the theory, the corresponding equation of the characteristic curves is expressed by:
