Understanding Additive Inverses and Operations

The video tutorial explains how to solve one-step equations using addition and subtraction, focusing on handling positive and negative numbers. It provides two examples: solving n + 19 = 6 and x + 10 = 4. The tutorial also introduces the concept of additive inverses as an alternative method for solving equations.

What is the first step in solving the equation n + 19 = 6?

• Divide both sides by 19

• Multiply both sides by 19

• Subtract 19 from both sides

• Add 19 to both sides

When solving n + 19 = 6, what is the result of 6 - 19?

• 13

• -13

• 25

• -25

Why do we change subtraction into addition when dealing with negative numbers?

• To simplify the calculation

• To make the equation more complex

• To avoid using negative numbers

• To make the equation longer
