Separation of variables

If solving a PDE using separation of variables, let's say the poisson equation, then it becomes x"/x+y"/y=0

That gets that x"/x=constant and likewise for y.

Now let's say after separation of variables of some problem I have x"/x+y"/y+yz"/z=0

Would I be able to say that x"/x=constant?
