You can put this solution on YOUR website!
3x + y = 8
y=-3x+8 (red line)
12x + 4y = 32
4y=-12x+32
y=-12x/4+32/4
y=-3x+8 (green line)
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+-3x+%2B8%2C+-3x+%2B8%29+ (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions -3x +8 and -3x +8).
These equations are identical.
