समीकरण (2x+5y=9) और (4x+10y=18) के लिए हलों की संख्या क्या होगी?
What will be the number of solutions for (2x+5y=9) and (4x+10y=18)?
Explanation opens after your attempt
Correct Answer
C. अनंत हल/Infinitely many solutions
Step 1
Concept
The second equation is (2) times the first so both lines are coincident. Coincident lines have infinitely many solutions.
Step 2
Why this answer is correct
The correct answer is C. अनंत हल / Infinitely many solutions. The second equation is (2) times the first so both lines are coincident. Coincident lines have infinitely many solutions.
Step 3
Exam Tip
दूसरा समीकरण पहले का (2) गुना है इसलिए दोनों रेखाएं संपाती हैं। संपाती रेखाओं में अनंत हल होते हैं।
