Solving Equations with Multiplicative and Additive Inverses

This video tutorial teaches how to solve equations using additive and multiplicative inverses. It begins with an introduction to these concepts, followed by a discussion on the importance of order of operations. The tutorial includes two examples demonstrating how to apply these inverses to solve equations, emphasizing the need to maintain equivalency by performing operations on both sides of the equation.

What is the additive inverse of 5?

• 1

• 0

• -5

• 5

Which of the following is the multiplicative inverse of 3?

• 3

• 0

• 1

• 1/3

Why is it important to follow the order of operations when solving equations?

• To ensure the equation is balanced

• To get the correct solution

• To make the equation simpler

• To avoid using inverses

In the equation 2X - 6 = 1, what is the first step to isolate X?

• Divide both sides by 2

• Subtract 6 from both sides

• Multiply both sides by 2

• Add 6 to both sides

How do you solve X/3 - 4 = 4 for X?

• Add 4 to both sides, then multiply by 3

• Subtract 4 from both sides, then divide by 3

• Multiply both sides by 3, then add 4

• Multiply both sides by 4
