Understanding Linear Equations and Long Division

The video tutorial explains how to solve a linear equation by isolating the variable. It begins by discussing the goal of manipulating the equation to have the variable on one side. The tutorial then covers undoing multiplication through division, specifically focusing on dividing by decimals using long division. The process of calculating the quotient is detailed, followed by verifying the solution to ensure accuracy. The tutorial concludes with a successful check of the solution.

What is the primary goal when solving a linear equation?

• To simplify the equation

• To make both sides of the equation equal

• To eliminate all numbers

• To find the value of the variable
