Open Middle: Systems of Linear Equations (3)

Your task:
Enter any integer value(s) ranging from -9 to 9 in the boxes below. The LARGE POINT that will appear is moveable. Try to create a setup that works!
Are there any digits you avoided using? If so, which one(s)? And why did you avoid using them?
Create another system of linear equations with its solution that is entirely different form the setup you built above.
