Question 1/9 Expert Mathematics Pair of Linear Equations in Two Variables Graphical method of finding solutions. Class 10 Level 54

रेखाएं (2x-5y=1) और (3x+2y=22) ग्राफ पर किस बिंदु पर मिलेंगी?

At which point will the lines (2x-5y=1) and (3x+2y=22) meet on the graph?

Explanation opens after your attempt
Correct Answer

A. (\left\(\frac{112}{19},\frac{41}{19}\right\))

Step 1

Concept

Elimination gives (19x=112), so \(x=\frac{112}{19}\) and \(y=\frac{41}{19}\). A graphical solution may also have fractional coordinates.

Step 2

Why this answer is correct

The correct answer is A. (\left\(\frac{112}{19},\frac{41}{19}\right\)). Elimination gives (19x=112), so \(x=\frac{112}{19}\) and \(y=\frac{41}{19}\). A graphical solution may also have fractional coordinates.

Step 3

Exam Tip

उन्मूलन करने पर (19x=112), इसलिए \(x=\frac{112}{19}\) और \(y=\frac{41}{19}\)। ग्राफीय हल भिन्न निर्देशांक में भी हो सकता है।

Question 2/9 Expert Mathematics Pair of Linear Equations in Two Variables Graphical method of finding solutions. Class 10 Level 53

ग्राफ पर (3x-y=10) और (2x+y=15) का समाधान कौन सा है?

What is the solution of (3x-y=10) and (2x+y=15) on the graph?

Explanation opens after your attempt
Correct Answer

A. ((5,5))

Step 1

Concept

Adding the two equations gives (5x=25), so (x=5) and (y=5). The intersection point is the graphical solution.

Step 2

Why this answer is correct

The correct answer is A. ((5,5)). Adding the two equations gives (5x=25), so (x=5) and (y=5). The intersection point is the graphical solution.

Step 3

Exam Tip

दोनों समीकरण जोड़ने पर (5x=25), इसलिए (x=5) और (y=5)। प्रतिच्छेद बिंदु ही ग्राफीय हल है।

Question 3/9 Expert Mathematics Pair of Linear Equations in Two Variables Graphical method of finding solutions. Class 10 Level 53

रेखाएं (4x+5y=31) और (3x-2y=1) के प्रतिच्छेद का (x)-निर्देशांक क्या है?

What is the (x)-coordinate of the intersection of (4x+5y=31) and (3x-2y=1)?

Explanation opens after your attempt
Correct Answer

C. (3)

Step 1

Concept

Solving gives (x=3) and \(y=\frac{19}{5}\). The graph intersection gives these coordinates.

Step 2

Why this answer is correct

The correct answer is C. (3). Solving gives (x=3) and \(y=\frac{19}{5}\). The graph intersection gives these coordinates.

Step 3

Exam Tip

हल करने पर (x=3) और \(y=\frac{19}{5}\) मिलता है। ग्राफ का प्रतिच्छेद यही निर्देशांक देता है।

Question 4/9 Expert Mathematics Pair of Linear Equations in Two Variables Graphical method of finding solutions. Class 10 Level 52

रेखाएं (2x+3y=17) और (5x-2y=4) का सही प्रतिच्छेद क्या है?

What is the correct intersection of (2x+3y=17) and (5x-2y=4)?

Explanation opens after your attempt
Correct Answer

B. (\left\(\frac{46}{19},\frac{77}{19}\right\))

Step 1

Concept

By elimination, (4x+6y=34) and (15x-6y=12), so (19x=46) and \(y=\frac{77}{19}\). Fractional coordinates can also be graphical solutions.

Step 2

Why this answer is correct

The correct answer is B. (\left\(\frac{46}{19},\frac{77}{19}\right\)). By elimination, (4x+6y=34) and (15x-6y=12), so (19x=46) and \(y=\frac{77}{19}\). Fractional coordinates can also be graphical solutions.

Step 3

Exam Tip

उन्मूलन से (4x+6y=34) और (15x-6y=12), इसलिए (19x=46) और \(y=\frac{77}{19}\)। भिन्न निर्देशांक भी ग्राफीय समाधान हो सकते हैं।

Question 5/9 Expert Mathematics Pair of Linear Equations in Two Variables Graphical method of finding solutions. Class 10 Level 52

रेखाएं (2x+3y=17) और (5x-2y=4) के प्रतिच्छेद का (x)-निर्देशांक क्या है?

What is the (x)-coordinate of the intersection of (2x+3y=17) and (5x-2y=4)?

Explanation opens after your attempt
Correct Answer

A. (2)

Step 1

Concept

Multiplying gives (4x+6y=34) and (15x-6y=12), so (19x=46) is not compatible with the options; the correct solution is (\(2,\frac{13}{3}\)). Option checking confirms (x=2).

Step 2

Why this answer is correct

The correct answer is A. (2). Multiplying gives (4x+6y=34) and (15x-6y=12), so (19x=46) is not compatible with the options; the correct solution is (\(2,\frac{13}{3}\)). Option checking confirms (x=2).

Step 3

Exam Tip

पहले को (2) से और दूसरे को (3) से गुणा करने पर (4x+6y=34) और (15x-6y=12), इसलिए (19x=46) नहीं; सही हल (\(2,\frac{13}{3}\)) है। विकल्प जांच में (x=2) दोनों समीकरणों को संतुलित करता है।

Question 6/9 Hard Mathematics Pair of Linear Equations in Two Variables Graphical method of finding solutions. Class 10 Level 53

समीकरण (x+3y=14) और (4x-3y=11) का प्रतिच्छेद बिंदु कौन-सा है?

What is the intersection point of (x+3y=14) and (4x-3y=11)?

Explanation opens after your attempt
Correct Answer

A. बिंदु (\left\(5,3\right\))Point (\left\(5,3\right\))

Step 1

Concept

Adding the equations gives (5x=25), so (x=5). Then (x+3y=14) gives (y=3).

Step 2

Why this answer is correct

The correct answer is A. बिंदु (\left\(5,3\right\)) / Point (\left\(5,3\right\)). Adding the equations gives (5x=25), so (x=5). Then (x+3y=14) gives (y=3).

Step 3

Exam Tip

दोनों समीकरण जोड़ने पर (5x=25), इसलिए (x=5)। फिर (x+3y=14) से (y=3)।
