Correct Answer

C. (y=3)

Step 1

Concept

Subtracting gives (3y=9), so (y=3). Remove equal (x) terms to get (y) directly.

Step 2

Why this answer is correct

The correct answer is C. (y=3). Subtracting gives (3y=9), so (y=3). Remove equal (x) terms to get (y) directly.

Step 3

Exam Tip

घटाने पर (3y=9), इसलिए (y=3)। समान (x) पदों को हटाकर सीधे (y) निकालें।
