Graphing One-Variable Inequalities

The video tutorial explains how to solve equations and graph them on a number line, using the example of 4x = 12, which results in x = 3. It then introduces inequalities, using real-life scenarios like height requirements for rides, and explains the different inequality symbols. The tutorial also covers how to graph inequalities on a number line, detailing the use of open and closed dots and the direction of arrows based on the inequality type.

What is the solution to the equation 4x = 12?

• x = 3

• x = 2

• x = 12

• x = 4
