Note Set 01b: A 3x3 $\mathbf{A}\vec{x}=\vec{b}$ example for the row, column, and matrix pictures.

We set up a 3x3 $\mathbf{A}\vec{x}=\vec{b}$ example for the row, column, and matrix pictures. We illustrate how 0, 1, or infinitely many solutions are possible (as is always the case for any size system). Solving these sytems is next. Control your emotions as best you can.
