समीकरणों (6x+9y=18) और (2x+3y=c) का कोई हल न हो, इसके लिए (c) का कौन-सा मान सही है?
For (6x+9y=18) and (2x+3y=c) to have no solution, which value of (c) is correct?
Explanation opens after your attempt
D. (c=8)
Concept
The first equation becomes (2x+3y=6). When (c=8), the left side is the same but the right side is different, so there is no solution.
Why this answer is correct
The correct answer is D. (c=8). The first equation becomes (2x+3y=6). When (c=8), the left side is the same but the right side is different, so there is no solution.
Exam Tip
पहला समीकरण (2x+3y=6) बनता है। (c=8) होने पर समान बायां पक्ष और अलग दायां पक्ष मिलेगा, इसलिए कोई हल नहीं।
