If the lines (2x+3y=12) and (4x+my=24) are coincident, what is (m)?यदि (2x+3y=12) और (4x+my=24) की रेखाएं संपाती हैं, तो (m) क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (6)(6)
The second equation is (2) times the first, so (m=6). In a coincident line, the coefficient of (y) also changes in the same ratio.दूसरा समीकरण पहले का (2) गुना है, इसलिए (m=6)। संपाती रेखा में (y) का गुणांक भी उसी अनुपात में बदलता है।
