Solving Multiplication Equations

Mr. Buffington teaches how to solve one-step multiplication equations, emphasizing the importance of checking work. He provides examples, including equations with negative numbers and decimals, and concludes with a recap of the steps involved.

What is the first step in solving a one-step multiplication equation?

• Subtract a constant from both sides

• Identify the variable

• Add a constant to both sides

• Multiply both sides by zero

In the equation 4X = 20, what operation is implied between 4 and X?

• Subtraction

• Addition

• Multiplication

• Division

What is the inverse operation used to solve 4X = 20?

• Divide by 4

• Subtract 4

• Add 4

• Multiply by 4

After solving 4X = 20, what should you do to verify your solution?

• Add 10 to the solution

• Divide the solution by 2

• Multiply the solution by 2

• Check the solution by substituting back into the original equation

What mistake was intentionally made when solving 9x = 81?

• Multiplying instead of dividing

• Using the wrong variable

• Saying x = 8 instead of x = 9

• Adding instead of subtracting

Why is it important to check your work when solving equations?

• To ensure the solution is correct

• To confuse the solver

• To make the process longer

• To avoid using a calculator

What is the result of dividing both sides of 9x = 81 by 9?

• x = 8

• x = 9

• x = 10

• x = 7

When solving -7x = 29, what is the first step?

• Subtract 7 from both sides

• Add 7 to both sides

• Divide both sides by -7

• Multiply both sides by -7

What is the approximate solution for -7x = 29?

• x ≈ -4.14

• x ≈ 4.14

• x ≈ 5.14

• x ≈ -5.14

What happens when you divide a positive number by a negative number?

• The result is positive

• The result is negative

• The result is undefined

• The result is zero
