Answer:
C) none
Step-by-step explanation:
The two lines are parallel (have the same slope (x-coefficient), but different y-intercepts). They have no point in common, hence there is no solution to the system of equations.
___
Another way to think about this: subtract the first equation from the second. You get ...
0 = 1
There are no values of the variables that will make this be true, hence no solutions.
