Solving Systems by Inspection

This Solving Systems by Inspection handout & reference also includes:

Can you solve a system by just looking at it? The previous lessons in the series taught three methods of solving systems of equations. Now learners discover they can determine the number of solutions of a system just by looking at it. Examples show problems with one solution, no solution, and infinitely many solutions.
