Question

The equation of the plane passing through the point $(1,1,1)$ and perpendicular to the planes $2x+y-2z=5$ and $3x-6y-2z=7$ is?

• A. $14x+2y-15z=1$
• B. $-14x+2y+15z=3$
• C. $14x-2y+15z=27$
• D. $14x+2y+15z=31$

Answer 1

The correct option is D $14x+2y+15z=31$

NOTE:Equation if the second plane should be $3x-6y-2z=7$

Hence option (D) is the correct anwer.
