Any advice/suggestions would be very helpful. 1. Consider the 2x2 system of linear equations= x+2y=3 2x-y=-4 - Examine the constants in the first equation and describe any patterns. Repeat for the second equation Where I am up to: 1st equation- 1, 2, 3 (+1) 2nd equation- 2, -1, -4 (-3) How do I describe the patterns? - Solve the above system. Display your solution graphically. What is the significance of the solution? I am assuming that solving the equation means finding out x and - so this can be done through matrices or simultaneous equations right? - Create and solve a few more systems similar to the example above. Comment on your solutions What exactly are similar solutions? - Make a proposition regarding this type of 2 x 2 system and prove it Totally lost on making a proposition?

In order to proceed, why don't you go ahead and solve them. Then, if you need help, post your solutions and we can proceed from there.
