Final answer:
The statement 22 + 7 = 22 + 7 illustrates the Addition Property of Equality, which states that adding the same number to both sides of an equation keeps the equation true and reflects the commutative nature of addition.
Step-by-step explanation:
A student has inquired about identifying the property of equality used to justify the statement 22 + 7 = 22 + 7. The correct answer is A) Addition Property of Equality. This property states that if you add the same number to both sides of an equation, the equation remains true. In this case, the equation indicates that adding 7 to 22 results in the same sum on both sides of the equal sign. This property confirms the equality of the two expressions and is a fundamental concept in algebra. It reflects the commutative property of addition (A+B = B+A) which means that you can add numbers in any order and still get the same result.
