You can solve both Algebraic Expressions and Linear Equations. They are derived from Algebra.

Introduction to Algebra
Algebra is a branch of mathematics that uses symbols and letters to represent numbers and quantities in formulas and equations. In Class 8, students build on their understanding of basic algebraic concepts.
Key Algebraic Concepts for Class 8
- Variables and Constants:
- Variables are symbols (like x or y) that represent unknown values.
- Constants are fixed values (like 5 or -3).
- Algebraic Expressions:
- An expression formed from variables, constants, and operators (like +, -, *, /).
- Example: 3x + 5 is an algebraic expression.
- Equations:
- A statement that two expressions are equal, often containing an equals sign (=).
- Example: 2x + 3 = 7 is an equation.
Types of Algebraic Operations
- Addition and Subtraction:
- Combine like terms to simplify expressions.
- Multiplication:
- Use the distributive property to multiply expressions.
- Division:
- Understand how to divide monomials and polynomials.
Solving Algebraic Equations
- One-Step Equations:
- Solve equations by performing inverse operations.
- Example: To solve x + 5 = 10, subtract 5 from both sides.
- Two-Step Equations:
- Involve two operations to isolate the variable.
- Example: To solve 2x + 3 = 11, first subtract 3, then divide by 2.
