1. The pair of linear equations y = 0 and y = -6 has
   1. a unique solution
   2. no solution
   3. infinitely many solution
   4. only solution (0,0) [CBSE 2020] [1 Mark]
2. Solve the following pair of linear equations:
   3x – 5y = 4
   2y + 7 = 9x [CBSE 2019] [2 Marks]
3. Solve the following pair of linear equations:
   3x + 4y = 10
   2x – 2y = 2 [CBSE 2019] [2 Marks]
4. In figure ABCD is a rectangle. Find the value of X and Y.
   [CBSE 2018] [2 Marks]
5. Solve the pair of equations:
   2/x + 3/y = 11, 5/x – 4/y = -7
   Hence, find the value of 5x – 3y. [CBSE 2020] [3 Marks]
6. Taxi charges in a city consist of fixed charges and the remaining charges depend upon the distance travelled. For a journey of 10 km, the charge paid is Rs 75 and for a journey of 15 km, the charge paid is Rs 110. Find the fixed charge and charges per km. Hence, find the charge of covering a distance of 35 km. [CBSE 2020] [3 Marks]
