किस समीकरण को (3) से गुणा करके (3x+2y=16) के साथ (x) हटाया जा सकता है?
Which equation can be multiplied by (3) to eliminate (x) with (3x+2y=16)?
Explanation opens after your attempt
B. (-x+y=2)
Concept
Multiplying (-x+y=2) by (3) gives (-3x+3y=6). This cancels (3x) by addition.
Why this answer is correct
The correct answer is B. (-x+y=2). Multiplying (-x+y=2) by (3) gives (-3x+3y=6). This cancels (3x) by addition.
Exam Tip
(-x+y=2) को (3) से गुणा करने पर (-3x+3y=6) बनता है। यह (3x) को जोड़कर हटा देगा।
