यदि \(x+2y\leq 12\) और \(x+2y\geq 12\) दोनों साथ दिए हों, तो संयुक्त हल क्या होगा?
If \(x+2y\leq 12\) and \(x+2y\geq 12\) are both given together, what is the common solution?
Explanation opens after your attempt
Correct Answer
B. रेखा (x+2y=12)Line (x+2y=12)
Concept
Together the two inequalities force equality (x+2y=12). Opposite inequalities with the same boundary often give the boundary line.
Why this answer is correct
The correct answer is B. रेखा (x+2y=12) / Line (x+2y=12). Together the two inequalities force equality (x+2y=12). Opposite inequalities with the same boundary often give the boundary line.
Exam Tip
दोनों असमानताएं मिलकर बराबरी (x+2y=12) को मजबूर करती हैं। विपरीत दिशाओं की समान सीमा अक्सर रेखा देती है।
