If two lines meet at (P(a,b)) and (a+b=9), (a-b=1), what is (P)?यदि दो रेखाएं (P(a,b)) पर मिलती हैं और (a+b=9), (a-b=1), तो (P) क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((5,4))((5,4))
Adding the two equations gives (2a=10), so (a=5) and (b=4). Coordinates of an intersection satisfy both equations together.दोनों समीकरण जोड़ने पर (2a=10), इसलिए (a=5) और (b=4)। प्रतिच्छेद के निर्देशांक समीकरणों को साथ-साथ संतुष्ट करते हैं।
