                  -
        1.     y =  x + 4            y = 2x + 6                          ______________________







        2.     10x + 8y = 2          5x + 4y = 1                         ______________________










        3.     2x + 18y = -9         4x + 18y = -27                      ______________________










        4.     y = x + 2             2x + y = 3                          _______________________









        5.     2x + 4y = -12         x + 2y = 6                          _______________________
