Understanding One-Variable Equations

The video tutorial explains how to solve one-variable equations by isolating the variable using inverse operations. It covers addition, subtraction, multiplication, division, and root operations. Three examples demonstrate solving for X and M, and handling cube root equations.

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

• Isolate the variable on one side

• Subtract a constant from both sides

• Multiply both sides by the same number

• Add a constant to both sides

Which operation is the inverse of addition?

• Division

• Multiplication

• Subtraction

• Square root

In the first example, what operation is used to isolate X?

• Multiplication

• Division

• Addition

• Subtraction

What is the result of 90 - 60 in the first example?

• 50

• 40

• 20

• 30

In the second example, what is the inverse operation used after addition?

• Square root

• Multiplication

• Division

• Subtraction

What is the value of M in the second example?

• 7

• 6

• 5

• 8

In the third example, what operation is used to isolate X after subtraction?

• Square root

• Cube root

• Addition

• Multiplication

What is the cube root of 216 in the third example?

• 5

• 6

• 7

• 8

What is the final value of X in the third example?

• 5

• 8

• 6

• 7

What is the key concept to remember when solving one-variable equations?

• Multiply both sides

• Use inverse operations

• Divide both sides

• Always add to both sides
