The system of simultaneous linear equations \(x-2 y+3 z=4,3 x+y-2 z=7,2 x+3 y+z=6\) has
- A infinitely many solutions
- B no solution
- C unique solution having \(z=2\)
- D unique solution having \(z=\frac{1}{2}\)
Answer & Solution
Correct Answer
(D) unique solution having \(z=\frac{1}{2}\)
Step-by-step Solution
Detailed explanation
\(D=\left|\begin{array}{ccc}1 & -2 & 3 \\ 3 & 1 & -2 \\ 2 & 3 & 1\end{array}\right|=42\) \(D \neq 0\) therefore unique solution…
