समीकरणों (5x+2y=18) और (15x+ay=54) के अनंत हल होने के लिए (a) का मान क्या होगा?

What is the value of (a) for the equations (5x+2y=18) and (15x+ay=54) to have infinitely many solutions?

Explanation opens after your attempt
Correct Answer

C. (6)

Step 1

Concept

For infinitely many solutions, (5/15=2/a=18/54) must hold. Therefore, (a=6) is correct.

Step 2

Why this answer is correct

The correct answer is C. (6). For infinitely many solutions, (5/15=2/a=18/54) must hold. Therefore, (a=6) is correct.

Step 3

Exam Tip

अनंत हल के लिए (5/15=2/a=18/54) होना चाहिए। इसलिए (a=6) सही है।
