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

A

` 3x - 4y - 1 = 0 `

B

` 3x - 4y - 4 = 0 `

C

` 4x - 3y - 4 = 0 `

D

` 4x - 3y - 1 = 0 `

Text Solution

Verified by Experts

` x - 2y + kz = 1 " " … (i) `
` 2x + y + z = 2 " " …(ii) `
` 3x - y - kz = 3 " " …(iii) `
Add (i) & (iii)
` 4x - 3y - 4 = 0 `
