The equation of the plane passing through the intersection of

[

…… (1)

[].

…… (2)

The required plane also passes through the point (1,1,1)

Substituting x = 1, y = 1, z = 1 in eq. (2),we have,

= (6 – 5k)

1 + 2k + 1 + 3k + 1 + 4k = 6 – 5k

3 + 9k = 6 – 5k

14k = 3

k =

Substituting the value k = in equation (1),We have,
