Solving One-Variable Equations and Inequalities

The video tutorial covers solving equations and inequalities in one variable, following Florida Benchmarks. It begins with an introduction to linear equations, explaining how to isolate the variable by performing opposite operations on both sides. An example of a more complex equation is provided, demonstrating the use of multiplication and division. The tutorial then transitions to solving inequalities, emphasizing the importance of flipping the inequality sign when multiplying or dividing by a negative number. The video concludes with a summary and acknowledgments.

What is the main goal when solving a linear equation?

• To eliminate all variables

• To find the value of the variable
