It probably means that one of the equations is a linear combination of the others/ To that extent, the system of equations is over-specified.

Add the two equations and get 4x = 12 so x = 3 and y = -1
It equals number in a a dozen. source:see how well you can do on a equations test
The system is inconsistent because there is no solution, i.e., no ordered pair, that satisfies both equations. You can see that this will be the case by seeing that their graphs have the same slope (2) but different y-intercepts (2 and 3/4 respectively). So the lines are parallel and will not intersect.

(3, 2) because x = 3 and y = 2
