Solving a two step equation

The video tutorial explains how to solve a two-step equation involving subtraction and division. It emphasizes the importance of following operations to isolate the variable. The process includes undoing subtraction by adding to both sides and then solving the equation by multiplying. The tutorial concludes with the final solution, demonstrating the value of the variable that satisfies the equation.

Why is it important to follow operations when solving a two-step equation?

• To change the equation's solution

• To make the problem more complex

• To ensure the equation remains balanced

• To avoid using a calculator

What is the first step in solving the equation a / 3.4 - 16 = 2.5?

• Multiply both sides by 3.4

• Subtract 16 from both sides

• Add 16 to both sides

• Divide both sides by 3.4

What property is used when adding 16 to both sides of the equation?

• Addition property of equality

• Division property of equality

• Subtraction property of equality

• Multiplication property of equality

After isolating the variable, what operation is needed to solve a / 3.4 = 18.5?

• Divide both sides by 3.4

• Subtract 3.4 from both sides

• Multiply both sides by 3.4

• Add 3.4 to both sides

What is the final value of 'a' that makes the equation true?

• 18.5

• 16

• 3.4

• 62.9
