(2(5x+3y)-7(x-y)+4x) को सरल करने पर (x) का गुणांक क्या होगा?
After simplifying (2(5x+3y)-7(x-y)+4x), what will be the coefficient of (x)?
Explanation opens after your attempt
B. (7)
Concept
The simplified form is (10x+6y-7x+7y+4x=7x+13y). So the coefficient of (x) is (7).
Why this answer is correct
The correct answer is B. (7). The simplified form is (10x+6y-7x+7y+4x=7x+13y). So the coefficient of (x) is (7).
Exam Tip
सरल रूप (10x+6y-7x+7y+4x=7x+13y) है। इसलिए (x) का गुणांक (7) है।
