What is the correct intersection point of (2x+3y=18) and (x-y=1)?समीकरण (2x+3y=18) और (x-y=1) का सही प्रतिच्छेद बिंदु कौन-सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ( (3,2) )( (3,2) )
Putting ( (3,2) ) gives (2(3)+3(2)=12), so it is not correct. The correct solution is ( (\frac{21}{5},\frac{16}{5}) ), so recalculation is needed in such options.( (3,2) ) रखने पर (2(3)+3(2)=12) है, इसलिए यह भी सही नहीं है। सही हल ( ( \frac{21}{5},\frac{16}{5}) ) होता है, अतः ऐसे विकल्पों में पुनः गणना जरूरी है।
