Warm Up
Take a look at this system (to the left) and enter these equations on the "quick graph" app.
Make sure you can clearly see what the solution would be.
Now, add the two equations together...yes, add them together as in y plus y and x + 1 plus 2x. Now graph this equation:
2y = 3x + 1 (you may have to solve for y).
What do you notice about all three equations?
Now subtract the two equations. Try graphing this equation. Again what do you notice?
Lesson
Today we will be learning our first algebraic method for solving a system of equations. Your assignment will be lesson #3 of the text.
Wrap Up
Please ensure that part 1 of the unit project is complete (and that you've submitted a question).
