Question 76957: Solve the system by graphing.
3x + y = 6
3x – y = 0

You can put this solution on YOUR website!
3x + y = 6 [isolate the y-term]
3x-3x+y=-3x+6
y= -3x+6
.
3x – y = 0 [isolate the y-term]
3x-3x-y=-3x
-y=-3x
-y/-1=-3x/-1
y=3x
.
.
The solution to this system is (1, 3). This is the point that the two lines have in common.
Graphing both equations:
