SAT Systems of Equations in 3 Levels: 600 vs 700 vs 800

This SAT systems of equations with "infinitely many solutions" looks like a 3-minute problem and takes about 10 seconds once you know what the question is actually asking. I solve the same official question three ways: the way a 600 scorer does it, the way a 700 scorer does it, and the way an 800 scorer does it. ▶ Not sure which tier you're solving at right now?
