In the linear equation 6x - 4y = 18 if x = 5 then what is y?

रेखीय समीकरण 6x - 4y = 18 में यदि x = 5 हो तो y का मान क्या होगा?

A) 2 / 2 B) 3 / 3 C) 4 / 4 D) 5 / 5
Show answer and explanation
Correct Answer

B. 3 / 3

Explanation

Putting x = 5 gives 30 - 4y = 18, so 4y = 12 and y = 3.

x = 5 रखने पर 30 - 4y = 18 इसलिए 4y = 12 और y = 3।
