यदि (2x+7y=36) और (2x+3y=20), तो (y) का मान क्या है?

If (2x+7y=36) and (2x+3y=20), what is the value of (y)?

Explanation opens after your attempt
Correct Answer

C. (y=4)

Step 1

Concept

Subtracting the second equation from the first gives (4y=16). Therefore (y=4).

Step 2

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).

Step 3

Exam Tip

पहले समीकरण से दूसरा घटाने पर (4y=16)। इसलिए (y=4)।
