If (x - 2)/3 = (x + 4)/5 then what is x?

यदि (x - 2)/3 = (x + 4)/5 हो तो x का मान क्या होगा?

A 8 / 8 B 10 / 10 C 12 / 12 D 14 / 14
Show answer and explanation
Correct Answer

D. 14 / 14

Explanation

Solving 5(x - 2) = 3(x + 4) gives 5x - 10 = 3x + 12 so x = 11.

5(x - 2) = 3(x + 4) से 5x - 10 = 3x + 12 और x = 11 नहीं बल्कि x = 11 है।
