Answer by checkley77(12844) (Show Source): You can put this solution on YOUR website!
2X+4Y=8
4Y=-2X+8
Y=-2X/4+8/4
Y=-X/2+2 (red line)
3X+6Y=12
6Y=-3X+12
Y=-3X/6+12/6
Y=-X/2+2 (GREEN LINE)
THESE 2 LINES ARE IDENTICAL THUS THERE IS NO UNIQUE SOLUTION BUT AN UNLIMITED NUMBER OF POSSIBLE SOLUTIONS FOR X & Y.
