That makes sense. 

Here's a shortcut way of looking at it...

3x - 2y = 6
6x - 4y = 14

divide second equation by two on both sides, leave the first alone: 

3x - 2y = 6
3x - 2y = 8

Uhohs. 

This is saying that 6 = 8 (Do you know why?)

Clearly 6 does not equal 8, and there are no solutions. :)
