Understanding Two-Step Equations

This video tutorial explains how to solve a two-step equation by performing opposite operations on both sides. It starts with isolating the variable using subtraction and then uses division to solve for the variable. The tutorial emphasizes the importance of applying operations to both sides of the equation to maintain balance.

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

• Multiply both sides by a variable

• Add a constant to both sides

• Perform an opposite operation on both sides

• Perform the same operation on both sides

What is the opposite operation of addition?

• Division

• Addition

• Multiplication

• Subtraction

After subtracting 5 from both sides, what is the resulting equation?

• x = 21

• 2x = 16

• x = 16

• 2x = 21

What is the opposite operation of multiplication?

• Addition

• Subtraction

• Division

• Multiplication

What is the value of x after solving the equation?

• x = 8

• x = 21

• x = 5

• x = 16
