समीकरणों (5x+4y=44) और (5x-y=14) से (y) का मान क्या है?

What is the value of (y) from (5x+4y=44) and (5x-y=14)?

Explanation opens after your attempt
Correct Answer

B. (y=6)

Step 1

Concept

Subtracting the second equation from the first gives (5y=30). Therefore (y=6).

Step 2

Why this answer is correct

The correct answer is B. (y=6). Subtracting the second equation from the first gives (5y=30). Therefore (y=6).

Step 3

Exam Tip

पहले समीकरण से दूसरा घटाने पर (5y=30) मिलता है। इसलिए (y=6)।
