1)   (3x + 1) - 7(1 - 2x)
       ------------------------       = 2
                    14
      3x + 1 - 7 + 14x = 28
                    17 x -6 = 28
                         17x = 28 + 6
                         17x = 34
                             x = 34/17
                             x = 2

3x - 1
3(2) - 1 = 6 -1 = 5 (B)
