सीमा रेखाओं (4x+y=20) और (x+2y=13) का प्रतिच्छेद कौन सा है?
What is the intersection point of the boundary lines (4x+y=20) and (x+2y=13)?
Explanation opens after your attempt
Correct Answer
D. (\left\(\frac{27}{7},\frac{32}{7}\right\))
Concept
Solving the two equations gives \(x=\frac{27}{7}\) and \(y=\frac{32}{7}\). The intersection should then be checked in the inequalities.
Why this answer is correct
The correct answer is D. (\left\(\frac{27}{7},\frac{32}{7}\right\)). Solving the two equations gives \(x=\frac{27}{7}\) and \(y=\frac{32}{7}\). The intersection should then be checked in the inequalities.
Exam Tip
दोनों समीकरण हल करने पर \(x=\frac{27}{7}\) और \(y=\frac{32}{7}\) मिलता है। प्रतिच्छेद को बाद में असमानताओं में जांचना चाहिए।
