How to solve a one step equation using the subtraction property of equality

The video tutorial explains how to solve a one-step equation using the substitution property of equality. It outlines four steps: circling the variable, defining the operation, using the inverse operation, and applying the subtraction property of equality. The tutorial emphasizes isolating the variable by using subtraction to cancel out terms, ensuring the equation remains balanced. The instructor provides a detailed explanation of each step, highlighting the importance of understanding the operations involved and the properties of equality.

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

• Circle the variable

• Add a constant

• Multiply by a coefficient

• Divide by a number

What operation is being performed on the variable in the equation 2L + 5?

• Subtraction

• Multiplication

• Addition

• Division

What is the inverse operation of addition?

• Multiplication

• Addition

• Subtraction

• Division

Why is the subtraction property of equality used in solving the equation?

• To add a constant to both sides

• To multiply both sides by a number

• To divide both sides by a coefficient

• To keep the equation balanced while isolating the variable

What happens to the equation when you subtract the same number from both sides?

• The equation becomes a multiplication problem

• The equation becomes unbalanced

• The variable disappears

• The equation remains the same
