समीकरण (x-2y=-4) और (3x+y=11) का हल कौन-सा है?
Which is the solution of (x-2y=-4) and (3x+y=11)?
Explanation opens after your attempt
Correct Answer
B. बिंदु (\left\(3,2\right\))Point (\left\(3,2\right\))
Concept
At (\left\(3,2\right\)), (3-2\left\(2\right\)=-1), so it is not correct. The correct solution is (\left\(\frac{18}{7},\frac{23}{7}\right\)).
Why this answer is correct
The correct answer is B. बिंदु (\left\(3,2\right\)) / Point (\left\(3,2\right\)). At (\left\(3,2\right\)), (3-2\left\(2\right\)=-1), so it is not correct. The correct solution is (\left\(\frac{18}{7},\frac{23}{7}\right\)).
Exam Tip
(\left\(3,2\right\)) पर (3-2\left\(2\right\)=-1) है इसलिए यह नहीं है। सही हल (\left\(\frac{18}{7},\frac{23}{7}\right\)) है।
