Review I still don't get it. Two step equations

This video tutorial explains how to solve two-step equations, which involve two operations. It begins with a basic problem and demonstrates the process of isolating the variable using inverse operations and the reverse order of operations. The tutorial addresses common mistakes students make, such as incorrect subtraction and misunderstanding equivalent equations. It also covers more complex examples involving negative numbers and emphasizes the importance of understanding the signs in front of numbers. The video aims to help students confidently solve two-step equations by understanding the underlying concepts.

What is the primary difference between one-step and two-step equations?

• Two-step equations involve two operations.

• Two-step equations have more variables.

• Two-step equations are always quadratic.

• Two-step equations require graphing.

When solving a two-step equation, which operation should you reverse first?

• Exponentiation

• Multiplication

• Addition or Subtraction

• Division

What is the result of dividing both sides of the equation 5X = 15 by 5?

• X = 3

• X = 5

• X = 15

• X = 0

Why is it incorrect to combine terms like 5X and -6 in a two-step equation?

• They are both variables.

• They are both coefficients.

• They are both constants.

• They are not like terms.

What should you do if you encounter a negative variable in a two-step equation?

• Ignore the negative sign.

• Add a positive number to both sides.

• Multiply or divide by -1 to isolate the variable.

• Subtract a negative number from both sides.

How can subtraction be rewritten to simplify solving two-step equations?

• As a division problem

• As an addition problem

• As a multiplication problem

• As an exponentiation problem

In the equation -3 - Y = 7, what is the correct first step to isolate Y?

• Add 3 to both sides

• Subtract 3 from both sides

• Multiply both sides by -1

• Divide both sides by -3
