Master Cramer’s Rule in 10 Minutes! 🔥 | Guaranteed 4 Marks in JEE Main

Описание: Cramer's Rule is one of the most important topics in Algebra for JEE Main and Class 12. A question on the "System of Linear Equations" appears in almost every single JEE shift. In this video, I simplify the concepts of Unique, Infinite, and No Solutions using a clear flowchart strategy.

​We also solve recent JEE Main Previous Year Questions (PYQs) to show you exactly how to tackle these problems in the exam.

​📝 In this video, we cover:
​00:08- Introduction: Why Cramer's Rule is important
​00:27 - Understanding the System of Linear Equations (3 Variables)
​01:33 - Cramer's Rule Formula (\Delta, \Delta_1, \Delta_2, \Delta_3)
​01:44 - The Master Flowchart: Classifying Number of Solutions
​02:13 - Condition for Infinite Many Solutions (\Delta=0)
​03:08 - Condition for No Solution
​04:38 - Homogeneous System of Equations (Trivial vs Non-Trivial)
​05:32 - Solved Example: JEE Main 2024 PYQ (Infinite Solutions)
​08:19 - Solved Example: JEE Main 2021 PYQ (Homogeneous System)
