# If the system of linear equations $x-2y+kz=1$$2x+y+z=2$$3x-y-kz=3$has a solution $(z,y,z), z\neq 0$ then $(x,y)$ lies on the straight line whose equation is : Option 1) $3x-4y-1=0$ Option 2) $4x-3y-4=0$ Option 3) $4x-3y-1=0$ Option 4) $3x-4y-4=0$

$x-2y+kz=1............(1)$

$2x+y+z=2............(2)$

$3x-y-kz=3............(3)$

add $(1)$ and $(3)$

$4x-3y=4$

Option 1)

$3x-4y-1=0$

Option 2)

$4x-3y-4=0$

Option 3)

$4x-3y-1=0$

Option 4)

$3x-4y-4=0$
