समीकरणों (4x+7y=41) और (4x+3y=25) से (y) का मान क्या है?
What is the value of (y) from (4x+7y=41) and (4x+3y=25)?
Explanation opens after your attempt
C. (y=4)
Concept
Subtracting the second equation from the first gives (4y=16). Therefore (y=4).
Why this answer is correct
The correct answer is C. (y=4). Subtracting the second equation from the first gives (4y=16). Therefore (y=4).
Exam Tip
पहले समीकरण से दूसरा घटाने पर (4y=16) मिलता है। इसलिए (y=4)।
