Answer:
The system of the equations has no solution; the two lines are parallel.
Step-by-step explanation:
The equations have the same slope. In standard form, this can be seen as the same coefficients for x and y. We will multiply the second equation by -12 to reveal this.

This means the equations are parallel and will never cross. There is no solution.
Answer:
It would be
-2+7x
Step-by-step explanation:
