Does your subject line apply to your post? That is, are the instructions for this exercise to "solve the system using an augmented matrix"?
If so, then a good first step would be to get all the variable terms on the left-hand side, with the x-terms first, followed by the y-terms.
How far have you gotten in this process (or some other process, if I have mis-guessed the instructions)? Please reply showing all of your steps. Thank you.
