Example: Solve x + 3y = 11 and 3x + 4y = 18.
Solution:
Ordered pairs for the graph y = x/3 + 11/3
Ordered pairs for y = (3/4)x + 18/4.
The straight lines x + 3y = 11 and 3x + 4y = 18 are intersecting at (2,3). Therefore the solution is (2,3). Directions: Write at least five examples of your own and solve them using graphical method.
