SOLUTION: Solve the system by graphing 2x � y = 4 4x � 2y =-8

Question 84278: Solve the system by graphing
2x � y = 4
4x � 2y =-8

Answer by checkley75(3666) (Show Source): You can put this solution on YOUR website!
2x-y=4, -y=-2x+4, y=2x-4 (red line)
4x-2y=-8, -2y=-4x-8, y=(-4x/-2)-(8/-2), y=2x+4 (green line)
(graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions y = 2x -4 and y = 2x +4).
According to the graphing --- there is no common solution.
