elimination
3x - 4y = 12
4x - 4y = 12
-------------- Subtract
-x = 0
x = 0
y = -3
-------
To graph, find 2 points for each eqn and draw a straight line thru them.
3x + 4y = 12
x...y
0...3 --> (0,3)
4...0 --> (4,0)
----------------
Do the same for the other eqn. Where they intersect is the solution.
