Question 192870: Plot the graph of the equations 2x - 3y = 5 and 4x - 6y = 21 and interpret the result.

2x - 3y = 5
-3y=-2x+5
y=-2x/-3+5/-3
y=2x/3-5/3 (red line)
-------------------------
4x - 6y = 21
-6y=-4x+21
y=-4x/-6+21/-6
y=2x/3-7/2 (green line)
-------------------------
(graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions 2x/3 -5/3 and 2x/3 -7/2).
Lines are parallel thus there is no unique (single solution) for x or y.
