If the lines (3x+5y=25) and (6x+my=50) are coincident, what is (m)?यदि (3x+5y=25) और (6x+my=50) की रेखाएं संपाती हैं, तो (m) क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (10)(10)
The second equation is (2) times the first, so (m=10). In a coincident line, the coefficient of (y) also changes in the same ratio.दूसरा समीकरण पहले का (2) गुना है, इसलिए (m=10)। संपाती रेखा में (y) का गुणांक भी उसी अनुपात में बदलता है।
