Class 10 Maths – Linear Equations in two Variables
Important Questions for Practice
1. If x = 3m – 1 and y = 4 is a solution of the equation x + y = 6. Then find the value of m. [Answer: m = 1]
2. What is the point of intersection of the line represented by 3x – 2y = 6 and the y-axis. [Answer: (0, -3)]
3. For what value of p, system of equations 2x + py = 8 and x + y = 6 have no solution. [Answer: p = 2]
4. A motor cyclist is moving along the line x – y = 2 and another motor cyclist is moving along the line x – y = 4. Find out their moving direction. [Answer: move parallel]
5. Find the value of k for which pair of linear equations 3x + 2y = –5 and x – ky = 2 has no solution. [Answer: k = -2/3]
6. Express y in terms of x in the expression 3x – 7y = 10. [Answer: y = (3x -10)/7]
7. If 2x + 5y = 4, write another linear equation, so that lines represented by the pair are coincident. [Answer: 4x + 10y = 8]
8. Check whether the graph of the pair of linear equations x + 2y – 4 = 0 and 2x + 4y – 12 = 0 is intersecting lines or parallel lines. [Answer: parallel]
9. If the lines 3x + 2ky = 2, and 2x + 5y + 1 = 0 are parallel, then find values of k. [Answer: k = 15/4]
10. If we draw lines of x = 2 and y = 3 what kind of lines do we get? [Answer: Intersecting lines]
11. Form a pair of linear equations for: The sum of the numerator and denominator of the fraction is 3 less than twice the denominator. If the numerator and denominator both are decreased by 1, the numerator becomes half the denominator. [Answer: x – y = – 3, 2x – y = 1]
12. For what value of p the pair of linear equations: (p + 2) x – (2p + 1) y = 3(2p – 1); 2x – 3y = 7 has a unique solution. [Answer: p ≠ 4]
13. Solve for x and y: x – y/2 = 3; and x/2 – 2y/3 = 2/3. [Answer: 4, 2]
