In the linear equation 2x + 3y = 12 if x = 3 then what is y?

रेखीय समीकरण 2x + 3y = 12 में यदि x = 3 हो तो y का मान क्या होगा?

A) 1 / 1 B) 2 / 2 C) 3 / 3 D) 4 / 4
Show answer and explanation
Correct Answer

B. 2 / 2

Explanation

Putting x = 3 gives 6 + 3y = 12 so 3y = 6 and y = 2.

x = 3 रखने पर 6 + 3y = 12 इसलिए 3y = 6 और y = 2।
