                   1.  Check whether the value given in the brackets is a solution to the given equation
                       or not:

                       (a) n + 5 = 19 (n = 1)

                       (b) 7n + 5 = 19(n = 2)

               2. Solve the equation by trial and error method:

                   3m – 14 = 4

               3. Write equations for the following statements:

               (i) The sum of numbers x and 4 is 9.

               (ii)The number b divided by 5 gives 6.

               (iii)Three-fourth of t is 15.
               4. Write the following equations in statement forms:


               (i) p + 4 = 15
               (ii) 2m = 7


               (iii) 3p + 4 = 25
               5. Set up an equation in the following cases:

               (i) Laxmi’s father is 49 years old. He is 4 years older than three times Laxmi’s age.
               (Take Laxmi’s age to be y years.)

               (ii) In an isosceles triangle, the vertex angle is twice either base angle. (Let the base
               angle be b in degrees. (Remember that the sum of angles of a triangle is 180 degrees).

               (iii)The teacher tells the class that the highest marks obtained by a student in her class
               is twice the lowest marks plus 7. The highest score is 87. (Take the lowest score to be
               l.)
