please solve ASAP. :(
Find the equation of the plane which passes through the line of intersection of the planes x+y−2z = 1 and 2x+y−4z = 3 and which is perpendicular to the plane x+y+z = 1
Equation of plane passing through the line of intersection of the above two planes is
This plane is perpendicular to Normals are also perpendicular
Direction ratios of normals of new plane are respectively
Direction ratios of normals of plane x+y+z-1=0 respectively
Since the planes are perpendicular,
So,
0
Substituting \lambda=0\ in equation of line , we get
This is the required equation of line.
