In the linear equation 10x + 5y = 65 if x = 4 then what is y?

रेखीय समीकरण 10x + 5y = 65 में यदि x = 4 हो तो y का मान क्या होगा?

A 3 / 3 B 4 / 4 C 5 / 5 D 6 / 6
Show answer and explanation
Correct Answer

C. 5 / 5

Explanation

Putting x = 4 gives 40 + 5y = 65 so 5y = 25 and y = 5.

x = 4 रखने पर 40 + 5y = 65 इसलिए 5y = 25 और y = 5।
