You can put this solution on YOUR website!
2x-y=1
-Y=-2X+1
Y=2X-1 (RED LINE)
8x-4y=-8
-4Y=-8X-8
4Y=8X+8
Y=8X/4+8/4
Y=2X+2 (GREEN LINE)
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+2x+-1%2C+2x+%2B2%29+ (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions 2x =1 and 2x +2).
These two lines are parallel thus no intersection & no unique solution.
