रेखाएँ (3x+2y=19) और (x-y=1) ग्राफ पर किस बिंदु पर मिलती हैं?
At which point do the lines (3x+2y=19) and (x-y=1) meet on the graph?
Explanation opens after your attempt
A. बिंदु (\left\(\frac{21}{5},\frac{16}{5}\right\))Point (\left\(\frac{21}{5},\frac{16}{5}\right\))
Concept
Using (x=y+1) from (x-y=1) gives \(y=\frac{16}{5}\) and \(x=\frac{21}{5}\). On the graph this is the intersection point.
Why this answer is correct
The correct answer is A. बिंदु (\left\(\frac{21}{5},\frac{16}{5}\right\)) / Point (\left\(\frac{21}{5},\frac{16}{5}\right\)). Using (x=y+1) from (x-y=1) gives \(y=\frac{16}{5}\) and \(x=\frac{21}{5}\). On the graph this is the intersection point.
Exam Tip
(x-y=1) से (x=y+1) रखकर \(y=\frac{16}{5}\) और \(x=\frac{21}{5}\) मिलता है। ग्राफ पर यही प्रतिच्छेद बिंदु होगा।
