Simplifying Equations and Operations

The video tutorial explains how to solve the linear equation 2 * 5x = 60 and determine which of the given options are valid simplifications using mathematical properties. Option A (10x = 60) and Option B (5x = 30) are valid simplifications, while Option C is not considered simpler. Option D is valid due to the associative property.

What is the main goal of Liette's problem-solving task?

• To find the value of x

• To simplify the given equation

• To create a new equation

• To solve a quadratic equation

How is the equation simplified in option A?

• By adding 5 to both sides

• By distributing the multiplication

• By subtracting 2 from both sides

• By dividing by 10

Which of the following is a correct simplified version of 2 * 5x = 60?

• 2x = 30

• 10x = 60

• 5x = 60

What mathematical operation is used to simplify the equation in option B?

• Multiplying both sides by 2

• Subtracting 5 from both sides

• Adding 10 to both sides

• Dividing both sides by 2

What happens to the '2' in the equation when simplifying option B?

• It is divided out from both sides

• It is subtracted from both sides

• It is multiplied by 5

• It is added to both sides

What is the result of dividing 60 by 2 in option B?

• 60

• 30

• 15

• 10

Why is option C not considered a valid simplification?
