Given 2 x-y+2 z=2, x-2 y+z=-4 , x+y+ z=4 , then the value of such that the given system of equation has no solution is

Options

  1. A-3
  2. B1
  3. C0
  4. D3

Correct answer

D. 3

Step-by-step solution

Since, the system has no solution. | array ccc 2 & -1 & 2 1 & -2 & -1 1 & 1 & array |=0 2(-2 +1)+1( +1)+2(3)=0 -4 +2+ +1+6=0 3 =9 =3
