Solving Linear Equations and Fractions

The video tutorial explains how to solve a linear equation with fractions in one variable. It demonstrates two methods: solving directly and solving by first clearing fractions. The tutorial provides a detailed step-by-step process for each method, ensuring the same solution is reached. It concludes with verifying the solution by substituting the value back into the original equation.

What is the first step in solving a linear equation in one variable?

• Add fractions to both sides

• Subtract the variable from both sides

• Isolate the variable on one side

• Multiply both sides by the variable
