समीकरण (px+6y=18) और (5x+3y=11) का अद्वितीय हल होने के लिए कौन-सी शर्त सही है?
Which condition is correct for (px+6y=18) and (5x+3y=11) to have a unique solution?
Explanation opens after your attempt
B. \(p \ne 10\)
Concept
For a unique solution \(p/5 \ne 6/3\) must hold. Therefore \(p \ne 10\) is the correct condition.
Why this answer is correct
The correct answer is B. \(p \ne 10\). For a unique solution \(p/5 \ne 6/3\) must hold. Therefore \(p \ne 10\) is the correct condition.
Exam Tip
अद्वितीय हल के लिए \(p/5 \ne 6/3\) होना चाहिए। इसलिए \(p \ne 10\) सही शर्त है।
