Linear Equation Solving Techniques

The video tutorial explains how to solve linear equations in one variable using two methods. The first method involves solving the equation with fractions, while the second method clears fractions at the start. Both methods aim to isolate the variable on one side of the equation, ultimately leading to the same solution. The tutorial emphasizes the importance of understanding the process of isolating the variable and provides a clear, step-by-step guide for each method.

What is the primary goal when solving a linear equation in one variable?

• To eliminate all numbers from the equation

• To isolate the variable on one side of the equation

• To convert the equation into a quadratic equation

• To find the reciprocal of the variable
