How to solve an equation using the addition property of equality

This video tutorial explains how to solve a one-step equation using the addition property of equality. It outlines four steps: circling the variable, identifying the operation, using the inverse operation, and checking the solution. The tutorial emphasizes understanding the addition property, which states that adding the same number to both sides of an equation keeps it balanced. By following these steps, students can solve equations effectively and verify their solutions.

What does the addition property of equality state?

• Dividing both sides of an equation by the same number keeps it balanced.

• Multiplying both sides of an equation by the same number keeps it balanced.

• Adding the same number to both sides of an equation keeps it balanced.

• Subtracting the same number from both sides of an equation keeps it balanced.

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

• Add a number to both sides.

• Subtract a number from both sides.

• Circle the variable.

• Identify the operation affecting the variable.

What operation should be used to solve the equation if subtraction is affecting the variable?

• Subtraction

• Multiplication

• Addition

• Division

After solving the equation, what should you do to ensure your solution is correct?

• Check the solution by substituting it back into the original equation.

• Add the solution to both sides of the equation.

• Multiply the solution by the original variable.

• Divide the solution by the original constant.

What is the result of adding 25 to both sides of the equation 113 = g - 25?

• g = 113

• g = 138

• g = 25

• g = 0
