: Please solve and graph for me please
3x -6y =9
x -2y =3 This question is from textbook Beginning Algebra 1A

Answer by checkley75(3666) (Show Source): You can put this solution on YOUR website!
3x-6y=9, -6y=-3x+9, y=-3x/-6+9/-6, y=x/2-1.5
x-2y=3, -2y=-x+3, y=-x/-2+3/-2, y=x/2-1.5 (these are for graphing). now multiply the second equation by -3 & solve thus:
3x-6y=9
-3x+6y=-9
-----------------------------------
0x+0y=0 this indicates that these 2 equations are the same!!!!!!
(graph 300x300 pixels, x from -10 to 10, y from -10 to 10, of TWO functions y = x/2 -1.5 and y = x/2 -1.5).
