Find the particular solution to the differential equation

(x + y - 4)dx - (3x - y - 4)dy = 0

that satisfies the initial condition y=1 when x=4

2. Relevant equations

3. The attempt at a solution

It's not a homog. or equal D.E., therefore I think it's substitution. I don't really know how to get this problem started.
