Find the scalar equations of the line passing through p(6, 0, 3), intersecting the line (x y z) = (1 2 3) + t(1 2 0) and perpendicular to it

The Attempt at a Solution
I don't know where to start with the problem, I tried using projections and then giving out equations for the scalar product of the two lines (which is 0) and the equations of the points of intersection, but there are so many variables I can't do anything with them. I'm stuck with this problem.
