Solving One-Step Equations: Addition and Subtraction

The video tutorial explains how to solve an equation by identifying the operation on the variable term, applying the inverse operation to both sides, and checking the solution by substitution. The process involves recognizing that adding three to the variable term requires subtracting three from both sides to isolate the variable. Finally, the solution is verified by substituting the value back into the equation.

What is the first step in solving the equation involving the variable term?

• Multiply both sides by 3

• Add 3 to both sides

• Subtract 3 from both sides

• Divide both sides by 3

What happens when you subtract 3 from both sides of the equation?

• The equation becomes unsolvable

• The variable term is eliminated

• A zero pair is created

• The equation becomes more complex

What is the result on the right side after subtracting 3 from 8?

• 3

• 8

• 5

• 0

Why is it important to check your solution after solving the equation?

• To find a different solution

• To make the equation more complex

• To change the variable

• To ensure the solution is correct

What should you do to verify the solution of the equation?

• Replace the variable with the solution and check the equation

• Subtract the solution from both sides

• Add the solution to both sides

• Multiply the solution by 3
