Solving One-Step Addition and Subtraction Equations

Mr. Buffington's lesson covers solving one-step addition and subtraction equations. The video explains the importance of following systematic steps to solve equations, emphasizing the use of inverse operations. It includes examples and practice problems to reinforce the concepts, ensuring students can handle both simple and complex equations. The lesson concludes with tips for success, highlighting the importance of practice and not skipping steps.

What is the first step in solving an addition equation?

• Divide both sides

• Add the numbers

• Multiply both sides

• Find the variable

In the equation 5 + x = 6, what should you do to isolate x?

• Divide both sides by 5

• Multiply both sides by 5

• Subtract 5 from both sides

• Add 5 to both sides

Why is it important to follow the steps even if the equation seems simple?

• To make the equation more complex

• To avoid using a calculator

• To save time

• To ensure accuracy

What is the opposite operation of addition?

• Multiplication

• Division

• Subtraction

• Addition

In the equation x - 4 = 8, what should you do to isolate x?

• Multiply both sides by 4

• Add 4 to both sides

• Subtract 4 from both sides

• Divide both sides by 4

What is the result of solving the equation x - 4 = 8?

• x = 4

• x = 8

• x = 16

• x = 12

In the equation x - (-4) = -16.8, what is the first step?

• Subtract -4 from both sides

• Add -4 to both sides

• Subtract 4 from both sides

• Add 4 to both sides

What is the value of x in the equation x - 7 = 9?

• x = 2

• x = 16

• x = -2

• x = -16

What should you do to both sides of the equation b - 5.2 = 10.5 to isolate b?

• Multiply by 5.2

• Add 5.2

• Subtract 5.2

• Divide by 5.2

What is the final value of b in the equation b - 5.2 = 10.5?

• b = 10.5

• b = 15.7

• b = 5.2

• b = 5.3
