Correct Answer

C. (4)

Step 1

Concept

From (2(4v+1)=(3v-4)+(6v-1)), (8v+2=9v-5), so (v=7). Use the twice-middle-term rule to find the variable.

Step 2

Why this answer is correct

The correct answer is C. (4). From (2(4v+1)=(3v-4)+(6v-1)), (8v+2=9v-5), so (v=7). Use the twice-middle-term rule to find the variable.

Step 3

Exam Tip

(2(4v+1)=(3v-4)+(6v-1)) से (8v+2=9v-5), इसलिए (v=7)। मध्य पद का दुगुना नियम लगाकर चर निकालें।
