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।

Step 1

Concept

From the first equation, (y=2x-6). Substituting gives (x+4x-12=8), so (x=4) and (y=2). The intersection point is the graphical solution.

Step 2

Why this answer is correct

The correct answer is A. ((4,2)). From the first equation, (y=2x-6). Substituting gives (x+4x-12=8), so (x=4) and (y=2). The intersection point is the graphical solution.

Step 3

Exam Tip

पहले से (y=2x-6), दूसरे में रखने पर (x+4x-12=8), इसलिए (x=4) और (y=2)। प्रतिच्छेद बिंदु ही ग्राफीय हल है।

Question 26/72 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 27/72 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 28/72 Expert Mathematics Pair of Linear Equations in Two Variables Graphical method of finding solutions. Class 10 Level 52

यदि दो रेखाएं (P(a,b)) पर मिलती हैं और (a+b=9), (a-b=1), तो (P) क्या है?

If two lines meet at (P(a,b)) and (a+b=9), (a-b=1), what is (P)?

Explanation opens after your attempt
Correct Answer

A. ((5,4))

Step 1

Concept

Adding the two equations gives (2a=10), so (a=5) and (b=4). Coordinates of an intersection satisfy both equations together.

Step 2

Why this answer is correct

The correct answer is A. ((5,4)). Adding the two equations gives (2a=10), so (a=5) and (b=4). Coordinates of an intersection satisfy both equations together.

Step 3

Exam Tip

दोनों समीकरण जोड़ने पर (2a=10), इसलिए (a=5) और (b=4)। प्रतिच्छेद के निर्देशांक समीकरणों को साथ-साथ संतुष्ट करते हैं।

Question 29/72 Expert Mathematics Pair of Linear Equations in Two Variables Graphical method of finding solutions. Class 10 Level 52

रेखाएं (4x-3y=11) और (2x+y=13) ग्राफ पर किस बिंदु पर मिलेंगी?

At which point will the lines (4x-3y=11) and (2x+y=13) meet on the graph?

Explanation opens after your attempt
Correct Answer

A. ((5,3))

Step 1

Concept

From (2x+y=13), (y=13-2x); substituting gives (10x=50), so ((5,3)). A graphical solution always satisfies both equations.

Step 2

Why this answer is correct

The correct answer is A. ((5,3)). From (2x+y=13), (y=13-2x); substituting gives (10x=50), so ((5,3)). A graphical solution always satisfies both equations.

Step 3

Exam Tip

(2x+y=13) से (y=13-2x), रखने पर (10x=50), इसलिए ((5,3))। ग्राफीय समाधान हमेशा दोनों समीकरणों को संतुष्ट करता है।

Question 30/72 Hard Mathematics Pair of Linear Equations in Two Variables Graphical method of finding solutions. Class 10 Level 54

रेखाएं (3x+y=15) और (x-y=1) का ग्राफ खींचने पर प्रतिच्छेद बिंदु कौन सा है?

What is the intersection point when the lines (3x+y=15) and (x-y=1) are graphed?

Explanation opens after your attempt
Correct Answer

B. ((4,3))

Step 1

Concept

From (x-y=1), (y=x-1), and (3x+x-1=15) gives (x=4), (y=3). The lines meet at ((4,3)) on the graph.

Step 2

Why this answer is correct

The correct answer is B. ((4,3)). From (x-y=1), (y=x-1), and (3x+x-1=15) gives (x=4), (y=3). The lines meet at ((4,3)) on the graph.

Step 3

Exam Tip

(x-y=1) से (y=x-1), और (3x+x-1=15) से (x=4), (y=3)। ग्राफ में दोनों रेखाएं ((4,3)) पर मिलेंगी।
