Answer:
No solutions. The lines are parallel.
Explanation:
y = -3x + 2
y = -3x - 7
I assume the question is to find the value of x that will make both equations equal.
We could set them equal to each other and solve for x, but a problem becomes immediately apparent:
-3x + 2 = -3x - 7
2 = -7
This may be true in the Andromeda Galaxy, but on Earth it is not.
A closer look at the equations tells us why these lines never intersect: they have the same slope, -3. They are parallel. Thus there is no common (x,y) that will solve both equations.
