समीकरण (2x+ay=18) रेखा (2x+3y=18) से संपाती हो, तो (a) का मान क्या होगा?
If (2x+ay=18) is coincident with (2x+3y=18), what will be the value of (a)?
Explanation opens after your attempt
B. (3)
Concept
For coincident lines, both equations must be in the same form. Therefore (a=3).
Why this answer is correct
The correct answer is B. (3). For coincident lines, both equations must be in the same form. Therefore (a=3).
Exam Tip
संपाती होने के लिए दोनों समीकरण समान रूप में होने चाहिए। इसलिए (a=3) होगा।
