Multiplying and Dividing with Equation Models

This video tutorial covers multiplying and dividing using equation models. It begins with an introduction to the topic, followed by detailed examples of solving multiplication problems like 4x = 16 and 6x = 6. The tutorial then moves on to division problems, demonstrating how to solve equations such as x/2 = 3 and -1 = 1/4x. The lesson concludes with a recap of the steps involved in solving these types of equations.

What is the main focus of today's lesson?

• Solving quadratic equations
