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
B. (y=6)
Concept
Subtracting the second equation from the first gives (5y=30). Therefore (y=6).
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).
Exam Tip
पहले समीकरण से दूसरा घटाने पर (5y=30) मिलता है। इसलिए (y=6)।
