How do I solve this problem by graphin
x+y=3
2x+y=1
------
They're 2 linear equations, meaning their graphs are straight lines.
-----
Find 2 points for each eqn.
x+y = 3
x...y
0...3 --> (0,3)
3...0 --> (3,0)
Plot the 2 points, draw a line thru them
--------
Do the same for the other eqn.
The intersection of the lines is the solution.
