Wad does this mean? And how to solve it? thanks in advance. find the equation of Cartesian for the straight line L intersects the surface P1:x+y+z=2 P2: -x+2y+z=4

(2) simultaneously for x, y and z (you will get a parameter in the solution). The solution gives the parametric equations of the required line.
