Answer:
x=-2, y=2
Step-by-step explanation:
we have
[tex]-8x+4y=24[/tex] -----> equation A
[tex]-7x+7y=28[/tex] ----> equation B
Solve the system by graphing
The solution of the system of equations is the intersection point both graphs
using a graphing tool
The solution is the point (-2,2)
see the attached figure
therefore
x=-2, y=2
