विलोपन विधि से (3x+2y=20) और (3x-2y=4) को जोड़ने पर (x) क्या होगा?
By elimination, what is (x) after adding (3x+2y=20) and (3x-2y=4)?
Explanation opens after your attempt
B. (x=4)
Concept
Adding gives (6x=24), so (x=4). Add opposite (2y) terms to eliminate them.
Why this answer is correct
The correct answer is B. (x=4). Adding gives (6x=24), so (x=4). Add opposite (2y) terms to eliminate them.
Exam Tip
जोड़ने पर (6x=24), इसलिए (x=4)। विपरीत (2y) पदों को जोड़कर हटाएँ।
