Illusion [34]

Answer:

No solutions.

Step-by-step explanation:

Both equations have the same slope, but are separated by virtue of their different values of b, the y-intercept.  The same slope means they are parallel lines.  Since the y-intercept is different, they do not overlap.

As they say, "Parallel line have a lot in common.  Too bad they'll never meet."
