Understanding and Solving Linear Equations

The video tutorial explains how to solve a linear equation by isolating the variable. It discusses the option of eliminating decimals by multiplying each term by a power of 10, transforming the equation into a simpler form. The tutorial then demonstrates solving the equation step-by-step, including subtraction and division, to find the solution. An alternative method using a calculator to handle decimals directly is also shown, emphasizing that both methods yield the same result.

What is the primary goal when solving a linear equation?

• To add more variables

• To convert it into a quadratic equation

• To isolate the variable on one side

• To eliminate all numbers
