Distributive Property and Solving Equations

The video tutorial introduces the distributive property of multiplication over addition, explaining that the sum of two numbers multiplied by a factor equals the sum of each number multiplied by the factor. It provides a numerical example and then extends the concept to include variables, demonstrating how to solve for a variable using the distributive property. The tutorial concludes with a recap of the key points covered.

What mathematical property is being discussed in the video?

• Associative Property

• Distributive Property

• Identity Property

• Commutative Property
