Two planes in 3D (usually) intersect in a line. Never just in
a single point.

Without parametric form - sure: just use Gaussian elimination and
you get the generic equation of the intersection line.
Without any kind of solving a system of equation - no.
Any algorithm solving your problem *is* a solver for a system
of equations, by the very definition of your problem.
