The video tutorial explains the subtraction property of equality, which states that subtracting the same number from both sides of an equation results in an equivalent equation. The instructor uses basic examples, such as 3 = 3 and X + 3 = 10, to demonstrate this property. By applying the subtraction property, the instructor shows how to maintain the truth of an equation and verify solutions. The tutorial concludes by emphasizing the usefulness of this property in solving equations.

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

• The equation becomes false.

• The equation remains equivalent.

• The equation becomes more complex.

• The equation loses its solution.

In the equation X + 3 = 10, what is the value of X after applying the subtraction property?

• X = 0

• X = 7

• X = 10

• X = 3

What is the result of subtracting 3 from both sides of the equation X + 3 = 10?

• X = 3

• X = 7

• X = 10

• X = 0

Why is the subtraction property of equality useful?

• It makes equations more complex.

• It helps in solving equations by maintaining equivalence.

• It changes the solution of the equation.

• It only works for equations with positive numbers.

Which of the following statements is true about equivalent equations?

• They have different solutions.

• They are only applicable to linear equations.

• They are not useful in solving equations.

• They have the same solution.
