Understanding One-Step Equations

The video tutorial introduces solving one-step equations, focusing on isolating variables using inverse operations. It explains the concept of equations and variables, and demonstrates how to solve equations by applying inverse operations like addition, subtraction, multiplication, and division. The tutorial includes practice problems and encourages independent practice to reinforce learning.

What is an equation?

• A statement that two expressions are equal

• A number that represents a quantity

• A mathematical operation like addition or subtraction

• A letter used to represent a known value

Which letter is most commonly used to represent a variable?

• D

• P

• X

• N

What does it mean to isolate a variable?

• To divide it by another variable

• To multiply it by a constant

• To get it by itself

• To add a number to it

What is the inverse operation of addition?

• Multiplication

• Subtraction

• Exponentiation

• Division

If you see multiplication in an equation, what should you do to isolate the variable?

• Add to both sides

• Divide both sides

• Subtract from both sides

• Multiply both sides

What is the inverse operation of division?

• Addition

• Subtraction

• Multiplication

• Exponentiation

In the equation 2X = 10, what operation would you use to solve for X?

• Subtract 2 from both sides

• Multiply both sides by 2

• Add 2 to both sides

• Divide both sides by 2

What is the result of solving the equation T/2 = 5?

• T = 2.5

• T = 10

• T = 5

• T = 15

What should you do if you see subtraction in an equation?

• Subtract from both sides

• Add to both sides

• Multiply both sides

• Divide both sides

What is the final step in the independent practice section?

• Discuss with a partner

• Review the video again

• Write and solve your own equation

• Solve a given equation
