The equation of the plane through the line of intersection of the planes ax + by + cz + d = 0 and and parallel to the line y=0 and z=0 is
The equation of a plane through the line of intersection of the planes ax + by + cz + d = 0 and is
This is parallel to the x-axis, i.e., y=0, z = 0.
Therefore,
or,
Putting the value of in (i), the required plane is
