**One step Algebra Equations**

Algebra - Writing mathematical phrases using letters to represent a number

eg. 2 + x = 3, 2 - x = 1

**Variable**- A letter that represents a number algebraic equation and expression

eg. x + 1 = 3

**Constan**t - The integers in an equation and expression

eg. 18 + x = 8

**Expression**- pattern (many answers)

eg. 8x

**Equation**- Has only one answer. Also has a equals sign : =

eg. 8x = 16

To solve one steps you need to

- first you need Isolate the variable
- make a zero pair with the constant
- Balance the equation
- Verify

**One-Step Equations :**

To solve two steps you need to

- Isolate the variable
- Cancel the constant
- Balance
- Simplify the variable
- Balance
- Verify

**Two Step Equations :**
