Options

  1. Ax+y+z=6, x+2 y-3 z=-4
  2. Bx+2 y-2 z=-1,4 x+4 y-5 z-3=0
  3. C3 x +2 y -3 z =0,3 x -6 y +3 z =-2
  4. D3 x+2 y-3 z=-2,3 x-6 y+3 z=0

Correct answer

D. 3 x+2 y-3 z=-2,3 x-6 y+3 z=0

Step-by-step solution

drs of line is 2,3,4 going through option, aligned & 2(1)+3(2)+4(-2)=0 & 2(4)+3(4)-4(5)=0 aligned
