Help on Systems of linear equations

First of all, Hello- I'm new to the site
I have a few questions which I need some help on. 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?

Re: Help on Systems of linear equations

Your description of the patterns seem quite adequate to me. 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.
