Answer:
The system of the equations has no solution; the two lines are parallel
Step-by-step explanation:
we have
----> equation A
-----> equation B
Solve the system by graphing
The solution is the intersection point both graphs
using a graphing tool
The lines does not intersect, the lines are parallel
see the attached figure
therefore
The system of the equations has no solution
