Mastering One Step Equations with Addition and Subtraction

This video tutorial covers solving one-step equations using addition and subtraction. It begins with an introduction to the concept of solutions in equations, followed by examples demonstrating how to determine if a given value is a solution. The tutorial explains the principles of equality and how they apply to solving equations by isolating variables. It concludes with a practical word problem to illustrate the application of these concepts.

Is x = 41 a solution to the equation x - 18 = 33?

• Yes

• Insufficient information

• No

• Only if x is a positive number

What is considered a solution to an equation?

• A value that, when substituted for the variable, makes the equation untrue.

• Any value that simplifies the equation.

• A value that, when substituted for the variable, makes the equation true.

• A random value of the variable.

What principle allows us to add the same number to both sides of an equation?

• Principle of Multiplication

• Principle of Division

• Principle of Equality

• Principle of Subtraction

How do we solve an equation by isolating the variable?

• By adding or subtracting the same value from both sides

• By multiplying both sides by the variable

• By guessing the value of the variable

• By dividing the entire equation by the variable
