व्यवस्था \(x\ge0\), \(y\ge0\), \(3x+y\le9\), \(x+y\le5\) में रेखाओं (3x+y=9) और (x+y=5) का प्रतिच्छेद कौन सा है?
In \(x\ge0\), \(y\ge0\), \(3x+y\le9\), \(x+y\le5\), what is the intersection of (3x+y=9) and (x+y=5)?
Explanation opens after your attempt
B. ( (2,3) )
Concept
Subtracting the two lines gives (2x=4), so (x=2) and (y=3). For vertices, solve the pair of linear equations.
Why this answer is correct
The correct answer is B. ( (2,3) ). Subtracting the two lines gives (2x=4), so (x=2) and (y=3). For vertices, solve the pair of linear equations.
Exam Tip
दोनों रेखाओं को घटाने पर (2x=4), इसलिए (x=2) और (y=3) है। शीर्षों के लिए रेखीय समीकरणों का युग्म हल करें।
