Writing Equations in One Variable (Lesson 7.1)

Learn how to write basic equations to model real-world situations. 

Solving Simple Equations Overview

Solving Basic Equations Using Addition & Subtraction

Equations are about relationships (no, not girlfriends and boyfriends!) between the two sides of the equation. Let's again use a scale example to help us understand. 

The example of a scale where we try to achieve balance helps to explain why we do the same thing to both sides of an equation. 

Solving Equations Using Addition or Subtraction (Lesson 7.2)

Solving Basic Equations Using Multiplication & Division

Solve Equations by Multiplying or Dividing. These problems involve decimals and fractions. 

Solving Equations Using Multiplication or Division (Lesson 7.3)

Writing Equations in Two Variables (Lesson 7.4)

Identifying the dependent and the independent variables in a word problem. Hint: independent variables are not influenced or changed by the other variable. 

Writing Equations with Two Variables from Word Problems

Filling out a Table from an Equation (You will pick your own values for the independent "x" variables to make your tables)
