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
- A infinite number of solutions
- B no solution
- C unique solution
- D finite number of solutions
Answer & Solution
Correct Answer
(B) no solution
Step-by-step Solution
Detailed explanation
\(A=\left|\begin{array}{ccc} 1 & 2 & 1 \\ 3 & 3 & -2 \\ 2 & 7 & 7 \end{array}\right|=1(21+14)-2(21+4)+1(21-6)=0\) So, system has no solution.
