Isolating Variables in Linear Equations

This video tutorial explains how to solve a linear equation with variable terms on both sides. It demonstrates two methods: isolating the variable on the right and left sides of the equation. The video also verifies the solution by substituting the value back into the original equation, ensuring the solution is correct.

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

• Add or subtract to isolate the variable term

• Add fractions to both sides

• Multiply both sides by zero

• Divide both sides by the variable
