The system of linear equations x+2 y+z=-3,3 x+3 y-2 z=-1,2 x+7 y+7 z=-4 has

Options

  1. Ainfinite number of solutions
  2. Bno solution
  3. Cunique solution
  4. Dfinite number of solutions

Correct answer

B. no solution

Step-by-step solution

A= | array ccc 1 & 2 & 1 3 & 3 & -2 2 & 7 & 7 array |=1(21+14)-2(21+4)+1(21-6)=0 So, system has no solution.
