समीकरणों (4x+ay=12) और (2x+3y=9) का कोई हल न हो, इसके लिए (a) का मान क्या होगा?
For (4x+ay=12) and (2x+3y=9) to have no solution, what should be the value of (a)?
Explanation opens after your attempt
C. (a=6)
Concept
For no solution, coefficients of (x) and (y) are proportional but constants are not. Since (4:2=2), (a=6) is correct.
Why this answer is correct
The correct answer is C. (a=6). For no solution, coefficients of (x) and (y) are proportional but constants are not. Since (4:2=2), (a=6) is correct.
Exam Tip
कोई हल न होने पर (x) और (y) के गुणांक समानुपाती होते हैं लेकिन स्थिरांक नहीं। (4:2=2), इसलिए (a=6) सही है।
