At which point do (3x+2y=25) and (x-3y=-11) meet on the graph?रेखाएं (3x+2y=25) और (x-3y=-11) ग्राफ पर किस बिंदु पर मिलती हैं?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((5,5))((5,5))
From the second equation, (x=3y-11). Substituting gives (9y-33+2y=25), so (y=5). Then (x=5), so the intersection is ((5,5)).दूसरे से (x=3y-11), पहले में रखने पर (9y-33+2y=25), इसलिए (y=5)। फिर (x=5), अतः प्रतिच्छेद ((5,5)) है।
