Ch2S2P3 | Solve 2×2 Systems – The Fast Elimination Trick Revealed!

Elimination made easy 🔥 In this video, a swarm of the smartest AI Agents in EducAgent Studio walks you step-by-step through Strang’s elimination method: choose the exact multiplier m to cancel x, convert the system into a clean triangular form, solve by back-substitution, and then instantly update the solution when the right-hand side flips from (6,0) to (-6,0). ✅ 📚 Reference: Chapter 2 - Section 2 - Problem 3 (Gilbert Strang - An Introduction to Linear Algebra - Fifth Edition) ✨ Watch more problems and improve your skills:    • Gilbert Strang - Linear Algebra   📌 What you’ll learn: ➗ How to pick the elimination multiplier m so the x-term disappears 📐 Turning a 2×2 system into a triangular system (upper-triangular form) 🔁 Back substitution to solve fast and accurately 🔄 How changing the right-hand side (from (6,0) to (-6,0)) changes the solution while keeping the same matrix 📊 Geometric meaning: two lines intersecting at the solution point 💬 Got a specific textbook problem you want solved next?
