###### Important Questions for Board Exams

- Solve for x and y: 3x + 2y = 11 and 2x + 3y = 4, also find p if p = 8x + 5y. [Answer: x = 5, y = – 2, p = 30]
- Solve the pair of linear equations by substitution method: x – 7y + 42 = 0 and x – 3y – 6 = 0. [Answer: 42, 12]
- Ram is walking along the line joining (1, 4) and (0, 6). Rahim is walking along the line joining (3, 4) and (1, 0). Represent on graph and find the point where both of them cross each other. [Answer: (2, 2)]
- Given the linear equation 2x + 3y – 12 = 0, write another linear equation in these variables, such that geometrical representation of the pair so formed is (i) parallel lines; (ii) coincident lines. [Answer: (i) 4x + 6y + 10 = 0, 4x + 6y – 24 = 0]
