    If you divide the second equation throughout by 3 we get 3x - 2y = 1 Now, is that consistent with the first equation, 3x - 2y = 7 ?

    No. Because the second equation implies 3x - 2y = 1 But the first equation is 3x - 2y = 7 If both equations where true, then that would imply that 7 = 1 which cannot be true!! We say that this system of equations is inconsistent, which means it leads to nonsense. Hence there are no solutions to both equations.
