In this lesson, you will manipulate equations and solve for a variable. You will also begin to determine which forms of equations are more useful than others.

When you finish this lesson, you will be able to:

• Solve for a particular variable, given an equation.
• Determine the more useful form of an equation.
• Explain the phrase “to solve for a variable.”

Here are the activities that will help you reach those goals:

• 1.8.1: Expressing Relationships Between Two Quantities
• 1.8.2: Identifying the Most Useful Form of an Equation
  • 1.8.2: Self Check
  • 1.8.2: Additional Resources
• 1.8.3: Writing Equations and Isolating Variables
  • 1.8.3: Self Check
  • 1.8.3: Additional Resources
• 1.8.4: Writing Equations Given Dimensions of Shapes

After that, you’ll practice and review.

• 1.8.5: Practice
