The equation of the plane through the intersection of the planes

x+y+z=1

and

2 x+3 y-z+4=0

and parallel to

X

-axis, is

View answer and explanation

Correct option: A

y-3 z+6=0

Option A (

y-3z+6=0

) is correct because the equation of the plane is found by taking a linear combination of the two planes and then using the condition that it is parallel to the X-axis.
