**Introduction to Algebra:**

Algebra is a branch of mathematics that deals with symbols and the rules for manipulating those symbols. It involves solving equations, finding unknown quantities, and analyzing patterns and relationships.

**Basic Concepts:**

1. **Variables:** In algebra, letters like x, y, or z are used to represent unknown quantities called variables. These variables can take on different values.

2. **Constants:** Constants are fixed values that do not change, like numbers.

3. **Expressions:** An expression is a combination of variables, constants, and mathematical operations (like addition, subtraction, multiplication, division) without an equal sign.

4. **Equations:** Equations are statements that show that two expressions are equal. They contain an equal sign (=).

**Operations in Algebra:**

1. **Addition and Subtraction:**

  – Example: x + 3 = 7 or 2y – 5 = 10

2. **Multiplication and Division:**

  – Example: 2x = 10 or 3y/2 = 6

3. **Solving Equations:**

  – To solve an equation, isolate the variable by performing the same operation on both sides of the equation until the variable is alone on one side.

  – Example: Solve for x in 2x + 5 = 11:

    – Subtract 5 from both sides: 2x = 6

    – Divide both sides by 2: x = 3

4. **Linear Equations:** Equations with variables raised to the power of 1.

  – Example: 3x + 2 = 8

5. **Quadratic Equations:** Equations involving squared terms (x^2).

  – Example: x^2 + 4x – 5 = 0

6. **Inequalities:** Statements that compare two expressions using inequality symbols like <, >, ≤, or ≥.

  – Example: 2x + 3 > 7

**Word Problems:**

Algebra is often used to solve real-world problems by translating verbal descriptions into mathematical equations or inequalities.

**Practice:**

1. Solve the equation 2x – 7 = 11.

2. Find the value of y if 3y + 4 = 16.

3. Solve the inequality 5x + 2 ≤ 17.

Remember, practice is key to mastering algebra!
