Solving Linear Equations and Fractions

This video tutorial explains how to solve a linear equation with variables on both sides by isolating the variable. It covers the decision-making process for eliminating terms, simplifying the equation, and solving a two-step equation. The tutorial also demonstrates converting the solution into a mixed number and emphasizes the importance of verifying the solution.

What is the first step in solving a linear equation with variables on both sides?

• Multiply both sides by zero

• Add the variables together

• Isolate the variable on one side

• Divide both sides by the variable

When deciding which variable term to eliminate, what is one option?

• Add 7 to both sides

• Subtract 7x from both sides

• Divide by 7x on both sides

• Multiply by 9x on both sides
