Which property justifies this statement?

x−4=x−4x−4=x−4

reflexive property of equality

substitution property of equality

transitive property of equality

symmetric property of equality

Option A is correct.

Reflexive property of equality that justifies the statement x-4 =x-4

Explanation:

Given the statement: x-4 = x-4

Reflexive property of equality states that the value is equal to itself.

Further, we can say that this property states that for all real numbers, a =a.

Therefore, by definition of reflexive property of equality:

x -4 = x- 4

Therefore, the property of equality that justifies the given statement x-4 = x-4 is: Reflexive property of equality
