Find the distance from the line L1 x = 2t + 2, y = 1-3t, z = 3+2t, to the line L2, which is the intersection between plane 2x + 2y -z = 1 and the plane x + 2z = 1. (Hint: One can find the equation of the intersection line by solving the two equations of the planes together with the substitution x = t.)
