Which property justifies this statement? if x = -6, then x + 6 = 0 a, reflexive b, division c, multiplication d, addition

Answer with Step-by-step explanation:

The Reflexive property states that for every real number x, x=x

Division property states that if a=b and we divide it by any non zero number c then also a/c=b/c

Multiplication property states that if a=b and we multiply it by any number c then also ac=bc

Addition property states that if a=b and we add it by any number c then also a+c=b+c

We are given that x= -6

Adding both sides by 6

⇒ x+6=0

Hence, it justifies the addition property.

Hence, correct option is:

D, Addition
