Mathematics Course
Topic: Algebra Basics
This course material covers the fundamental concepts of Algebra. It is designed for students to
understand the rules of algebra, practice key problems, and test themselves with exercises.
Key Concepts:
1. Variables: Symbols that represent numbers (e.g., x, y).
2. Expressions: Combinations of numbers, variables, and operations (e.g., 2x + 3).
3. Equations: A statement that two expressions are equal (e.g., 2x + 3 = 7).
4. Solving equations: Isolating the variable to find its value.
Example:
Solve: 2x + 3 = 7
Step 1: Subtract 3 from both sides → 2x = 4
Step 2: Divide by 2 → x = 2
Practice Questions:
1. Solve: x + 5 = 12
2. Solve: 3x - 4 = 11
3. If 2x + 3 = 15, find x
4. Simplify: 2(x + 3) + 4
5. Solve: 5x = 25
Answer Key:
1. x = 7
2. x = 5
3. x = 6
4. 2x + 10
5. x = 5
