Lesson 1: Understanding Variables 🌟
Variables are symbols or letters used to represent unknown numbers or values. In algebra, variables allow you to write expressions and equations that define relationships between different quantities.
Example: Simple Algebra Equation
Consider the equation x + 3 = 7. To solve it, you would subtract 3 from both sides to find that x = 4.
Lesson 2: The Art of Equations 🎨
Equations are mathematical statements that assert the equality of two expressions. Learning to manipulate equations is key to solving algebraic problems.
Example: Solving a Linear Equation
Solve for y: 2y - 6 = 10 by adding 6 to both sides and then dividing by 2, resulting in y = 8.
