Please note that if you mult. the first equation by 2, you get 6x-4y= 6, which is almost but not quite the same as the second equation. It should be obvious that 6x-4 in the first equation are the same expression as 6x-4 in the second equation. 6x-4 cannot = 6 and also =1 at the same time, so this system has NO solution. The 2 lines never intersect.
