               SUBTOPICS: Recap

               1. Solve the following equations by trial and error method


               3m – 14 = 4

               2. Give first the step you will use to separate the variable and then solve the equation


               (a) y + 4 = 4

               (b) y + 4 = – 4

               3. Solve the following equations


               (a) – 4(2 + x) = 8

               (b) 4(2 – x) = 8


                                                                  ଵ
               4. Verify that x = 8 is the solution of the equation   x + 7 = 11
                                                                  ଶ
               5. Solve 3(x – 1) = 2x – 11 and check the result..
