1
Solve equations mentally such as
 x + 6 = 9            x - 4 = 12        5x = 15        x/6 = 3
Solve equations such as the following showing some method
2x + 9 = 29        3x - 1 = 8  
2x = 20               3x = 9
x = 10                  x = 3


           
 2 Solve equations with brackets such as the following showing some method
3(x + 1) = 21            4(2x - 1) = 16
x + 1 = 7                  2x - 1 = 4
x + 6                          2x = 5
                                   x = 2.5

Solving simple equations where the x is on both sides of the equation by taking an x off both sides of the equation until there are only x's on one side
2x + 5 = x + 12                     5x - 3 = 2x + 6
x + 5 = 12                              4x - 3 = x + 6
      x = 7                                 3x - 3 = 6
                                                  3x = 9
                                                    x = 3
