1. Solve 11x + 1 5y + 23 = 0 , 7x – 2y – 20 = 0 by substitution method

2. Draw the graph of the equations 4x – 5 y + 16 = 0 and 2x + y – 6 = 0 and also determine the vertices of the triangle formed by these lines and the x axis.

3. Solve 2x – 5y + 8 = 0, x – 4y + 7 = 0 by substitution method

4. Two years ago Salim was thrice old as his daughter and six years later he will be four years older than twice her age. How old are they now.

5.  A fraction becomes 5/6 if 1 is added to each of the numerator and denominator. However if we subtract 5 from each, the fraction becomes 2/3  . Find the fraction.
