Mastering One-Step Equations with Addition and Subtraction

The video tutorial explains how to solve one-step equations using addition and subtraction. It introduces the concept of isolating the variable by using inverse operations and emphasizes the importance of maintaining balance in equations. The tutorial covers examples with both positive and negative numbers, demonstrating how to handle zero pairs effectively.

What is the first step in solving one-step equations?

• Multiplying both sides by 2

• Adding 5 to both sides

• Dividing both sides by 2

• Splitting the equation into two sections

In the equation X + 5 = 12, what operation should be performed to isolate X?
