Understanding One-Step Equations

Mr. Buffington explains how to solve one-step equations using inverse operations. He covers the basic principles of inverse operations, such as addition being the opposite of subtraction and multiplication being the opposite of division. The video provides step-by-step instructions for solving equations involving addition, subtraction, division, and multiplication. Each section includes examples to illustrate the process, emphasizing the importance of maintaining balance in equations by performing the same operation on both sides.

What is the inverse operation of addition?

• Multiplication

• Division

• Subtraction

• Exponentiation

When solving the equation X + 2 = 5, what should be done to both sides to isolate X?

• Add 2

• Divide by 2

• Subtract 2

• Multiply by 2

In the equation X - 7 = 12, what operation should be performed to solve for X?

• Add 7 to both sides

• Subtract 7 from both sides

• Multiply both sides by 7

• Divide both sides by 7

If N is divided by 3, what operation will help solve for N?

• Divide both sides by 3

• Multiply both sides by 3

• Subtract 3 from both sides

• Add 3 to both sides

What is the result of multiplying both sides of the equation N/3 = 71 by 3?

• N = 213

• N = 35.5

• N = 71

• N = 142

In the equation 5Y = 30, what operation should be performed to solve for Y?
