You can put this solution on YOUR website!
Graph each line and look for points of intersection.
+graph%28+300%2C+300%2C+-5%2C+5%2C+-5%2C+5%2C+3x-4%2C+-3x%2B2%29+
Looks like (1,-1) is a solution to this system of equations.

Verify by plugging (1,-1) into both equations.
y=3x-4
-1=3%281%29-4
-1=-1
True.
y=-3x%2B2
-1=-3%281%29%2B2
-1=-1
True.
(1,-1) is the solution.

+graph%28+300%2C+300%2C+-5%2C+5%2C+-5%2C+5%2C+%285%2F4%29x-2%2C+%285%2F4%29x-1%29+
There are no points of intersection.
There is no solution for this system of equations.
