Answer by checkley77(12844) (Show Source): You can put this solution on YOUR website!
2x-6y=11 MULTIPL BY 3
-3x+9y=-18 MULTIPLY BY 2 & ADD.
6x-18Y=33
-6X+18Y=-36
------------------------
0X+0Y=-3 NO SOLUTION & IF PLOTTED WOULD BE PARALLEL LINES AS SHOWN BELOW:
-6y=-2x+11
y=-2x/-6+11/-6
y=x/3-11/6 (red line)
-3x+9y=-18
9y=3x-18
y=3x/9-18/9
y=x/3-2 (green line)
(graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions x/3 -11/6 and x/3 -2).
