You can put this solution on YOUR website!
Here is a graph of the two lines, red line is y = -x + 3, green line is y = x + 1
:
+graph%28+300%2C+200%2C+-10%2C+10%2C+-10%2C+10%2C+-x%2B3%2C+x%2B1%29+
:
point of intersection looks like (1, 2)
:
set both equations = to each other
:
-x + 3 = x+ 1
:
2x = 2
:
x = 1
:
the solution is x = 1, y = 2
