we know that, the equation of a plane passing through the line of intersection of two planes

and

is given by

So the equation of the plane passing through the line of intersection of given two planes

and is given by

…… (1)

As given that, plane (1) is passing through the point 2 so

(2)(1) + (1)(3) + ( – 1)( – 1) + k[(2)(0) + (1)(1) + ( – 1)(2)] = 0

(2 + 3 + 1) + k(1 – 2) = 0

6 – k = 0

k = 6

put the value of k in equation (1)

So, the equation of the required plane is
