Solution:
As we can see the system is not resolvable because not all the lines intersect together in a common
point.
If the set of equations rights-hand sides are zero, as follows:
0
0
0

, then there is no any non-zero
choice of right hand sides that allows the three lines to intersect at the same point because all the three
lines intersects only at the origin (0,0).
