Operations with Negative Numbers and Equations

The video tutorial covers solving two-step equations, starting with basic examples and progressing to more complex problems involving combining like terms and using the distributive property. The instructor emphasizes the importance of isolating the variable and applying inverse operations to solve equations. Key techniques include addition, subtraction, multiplication, and division, as well as combining like terms and using the distributive property to simplify equations.

What is the first step in solving a two-step equation?

• Add or subtract to isolate the variable

• Multiply both sides by the same number

• Divide both sides by the same number

• Combine like terms

When isolating the variable in a two-step equation, what operation is typically performed after addition or subtraction?

• Subtraction

• Division

• Addition

• Multiplication

How do you combine the terms 8x and -6x?

• By multiplying them to get -48x^2

• By subtracting them to get 2x

• By adding them to get 14x

• By dividing them to get -1.33

What is the result of dividing a negative number by a positive number?

• The same negative number

• Zero

• A negative number

• A positive number

What is the purpose of the distributive property in solving equations?

• To multiply terms across parentheses

• To add terms together

• To subtract terms from each other

• To divide terms equally

In the equation 2(1 - 5x), what is the result of applying the distributive property?

• 2 - 10x

• 2 + 10x

• 1 - 5x

• 10x - 2

What is the result of combining the terms 2 and 4 in the equation 2 + 4 - 10x = -8?

• 8

• 6

• 12

• 10

What is the final step in solving the equation -10x = -14?

• Multiply both sides by -10

• Subtract 10 from both sides

• Add 10 to both sides

• Divide both sides by -10

What is the result of dividing -14 by -10?

• 0.7

• -0.7

• 1.4

• -1.4

What is the simplified form of the fraction -7/-5?

• 1.4

• -1.4

• 7/5

• -7/5
