For which of the following ordered pairs \((\mu, \delta)\) the system of linear equations \(x+2 y+3 z=1\) ; \(3 x+4 y+5 z=\mu\) ; \(4 x+4 y+4 z=\delta\) is inconsistent?
- A \((1,0)\)
- B \((4,6)\)
- C \((3,4)\)
- D \((4,3)\)
Answer & Solution
Correct Answer
(D) \((4,3)\)
Step-by-step Solution
Detailed explanation
\(2 \times(\text { ii })-2 \times(i)-(\text { iii })\) \(0=2 \mu-2-\delta\) \(\Rightarrow \delta=2(\mu-1)\)
