You can put this solution on YOUR website! 3x = y +3
y+3 = 3x
y = 3x -3
.
6x -2y = 3
-2y = -6x +3
y = 3x -3/2
.
The slope of each equation is the same, so they are parallel.
.
They have a different y-intercept, so they have no points in common, which means there is no solution.
.
In the following graph:
y = 3x-3 is red
y = 3x -3/2 is green
