Lesson 2 equips you with tools to simplify complex algebraic expressions. By combining like terms and applying the distributive property, you can transform intricate equations into elegant solutions.

## Embarking on an Equation Adventure

Equation Essentials

An equation is a mathematical sentence that asserts the equality of two expressions. Solving an equation involves finding the value of the variable that makes the equation true. Think of equations as fascinating puzzles waiting to be solved!

Balancing Act: Solving Equations

Imagine equations as scales – your goal is to keep both sides balanced. By performing the same operation on both sides, you maintain equilibrium and unveil the hidden value of the variable.

## Cracking the Code: Examples from the Answer Key

Example 1: Simplifying Expressions

Consider the expression: 3x + 2 – x + 4x – 5. To simplify, combine like terms: 3x – x + 4x + 2 – 5 = 6x – 3.

Example 2: Solving an Equation

Let’s tackle the equation: 2x + 7 = 15. To solve for x, subtract 7 from both sides: 2x = 8. Now, divide by 2: x = 4.
