Solving One-Step Equations by Adding and Checking

The video tutorial explains how to solve a simple linear equation by identifying the operation on the variable term, applying the inverse operation to isolate the variable, and verifying the solution. The process involves recognizing zero pairs and maintaining the balance of the equation by performing the same operation on both sides. The solution is checked by substituting the value back into the original equation to ensure correctness.

What is the first step in solving the equation when the variable is subtracted by 5?

• Divide by 5

• Multiply by 5

• Add 5

• Subtract 5

What is a zero pair in the context of solving equations?

• Two numbers that multiply to 1

• Two numbers that add to 10

• Two numbers that add to 0

• Two numbers that subtract to 5

Why is it important to perform the same operation on both sides of an equation?

• To change the variable

• To simplify the equation

• To maintain the balance of the equation

• To make the equation more complex

After isolating the variable, what should be done next to ensure the solution is correct?

• Multiply the solution by 2

• Add 5 to the solution

• Subtract the solution from 10

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

What is the solution to the equation after performing the necessary operations?

• X = 11

• X = 5

• X = 16

• X = 21
