Equations and Finding the Unknown | हिंदी व्याख्या | Class 7 Ganita Prakash II | NCERT Maths 2025

Описание: Master the basics of Algebraic Equations! 📐In this fun and engaging lesson, Prof. Analysis breaks down the fundamental concepts of equations from the Class 7 Ganita Prakash II (NCERT 2025) curriculum. If you’ve ever wondered what "x" really is or why we use the equal sign, this video is for you! Here, I have explained ALL ABOUT Equations alongs with difference with IDENTITY, Algebraic Expression.

NOTE - Where should we add, subtract , multiply or divide - I have discussed this in detail in previous video. Check 12:29 to 14:44 of this video    • Ch7 Finding the Unknown (part 3) | हिंदी व...  

In this video, we cover:
✅ The Definition of an Equation: Understanding the statement of equality between two algebraic expressions.
✅ LHS vs. RHS: Breaking down the Left Hand Side and Right Hand Side.
✅ How to Solve an Equation: Learning the art of isolating the variable using addition, subtraction, multiplication, and division on both sides.
✅ True vs. False Equations: Why $5/5 = 1$ is a valid equation but $3 = 4/3$ is a false one.
✅ Types of Equations: A quick look at Linear, Quadratic, and Cubic equations, as well as equations with No Solution (Contradictions) and Infinite Solutions (Identities).
✅ Higher Math Sneak Peek: Introduction to System of Equations and solving for multiple variables.

Why watch this? Perfect for Class 7 students following the new NCERT syllabus. Simple Hindi explanations mixed with English technical terms. Practical examples that make math feel like solving a puzzle!
