Consider three planes

P_1: x-y+z=1, P_2: x+y-z=-1

and P_3: x-3 y+3 z=2
Let L_1, L_2, L_3 be the lines of intersection of the planes
P_2 and P_3, P_3 and P_1, P_1 and P_2, respectively.
Statement I Atleast two of the lines L_1, L_2 and L_3 are
non-parallel.
Statement II The three planes do not have a common
point.
