The planes `bx-ay=n,cy-bz=l,az-cx=m` intersect in a line if___

Under what condition do the planes bx-ay=n,cy-bz=l,az-cx=m intersect in a line?

Under what condition do the planes bx-ay=n,cy-bz=l,az-cx=m interest in a line?

The planes bx - ay = n, cy - bz = I, az - cx= m intersect in a line if

The planes x=cy+bz,y=az+cx,z=bx+ay intersect in a line if (a+b+c)^(2) is equal to

If the planes y=az+cx, x=cy+bz+z=bx+ay meet in a line show that the line of intersection of these planes is x/sqrt(1-a^2)=y/sqrt(1-b^2)=z/sqrt(1-c^2)

If the planes x=cy+bz,y=az+cx and z=bx+ay pass through a line then a^(2)+b^(2)+c^(2)+2abc is equal to

If the planes x-cy-bz=0, cx-y+az=0 and bx+ay-z=0 pass through a line, then the value of a^2+b^2+c^2+2abc is

If the planes x-cy-bz=0, cx-y+az=0 and bx+ay-z=0 pass through a line, then the value of a^2+b^2+c^2+2abc is….

If the planes x-cy-bz=0, cx-y+az=0 and bx+ay-z=0 pass through a line, then the value of a^2+b^2+c^2+2abc is
