how many solutions does the system have? -3x+6y=10 and -3x+6y=-4

OpenStudy (anonymous):

Well, you would need to solve this system either via elimination or substitution, and then plug back in to see if they all check through (you shouldn't have any extraneous solutions).

ZERO solutions, NO SOLUTION

OpenStudy (solomonzelman):

it says that -3x+6y equals 10 and also equals -4 but same thing can't equal -4 and 10 at once.
