यदि \(x+3y\leq 9\) और \(x+3y\geq 9\) दोनों साथ दिए हों, तो संयुक्त हल क्या होगा?
If \(x+3y\leq 9\) and \(x+3y\geq 9\) are both given together, what is the common solution?
Explanation opens after your attempt
D. रेखा (x+3y=9)Line (x+3y=9)
Concept
Together the two inequalities force equality (x+3y=9). Opposite inequalities with the same boundary often give only the line.
Why this answer is correct
The correct answer is D. रेखा (x+3y=9) / Line (x+3y=9). Together the two inequalities force equality (x+3y=9). Opposite inequalities with the same boundary often give only the line.
Exam Tip
दोनों असमानताएं मिलकर बराबरी (x+3y=9) को मजबूर करती हैं। विपरीत दिशाओं की समान सीमा अक्सर केवल रेखा देती है।
