The Addition Property of Equality states that if you add the same number to both sides of an equation the two sides remain equal. Source- My mathbook.
division property of equality or multiplication property, if you multiply by the reciprocal
Addition identity.
Division Property of Equality
The multiplicative property of equality. Multiply each side by -1/3.
The reflexive property of relations is not the same as the addition property of equality.

A # that is + and is= ex 5=5
A # that is + and is= ex 5=5
You should state the property used, such as distributive property of multiplication over addition or addition property of equality, etc.
Why? - Mainly to help in solving equations.
Addition Property of Equality (APOE)
Properties of EqualitiesAddition Property of Equality (If a=b, then a+c = b+c)Subtraction Property of Equality (If a=b, then a-c = b-c)Multiplication Property of Equality (If a=b, then ac = bc)Division Property of Equality (If a=b and c=/(Not equal) to 0, then a over c=b over c)Reflexive Property of Equality (a=a)Symmetric Property of Equality (If a=b, then b=a)Transitive Property of Equality (If a=b and b=c, then a=c)Substitution Property of Equality (If a=b, then b can be substituted for a in any expression.)
The addition of the opposite, to both sides of the equation. keep it equal
6z+28=12z+10 6z-12z=10-28 addition property of equality. -6z=-18 simplification z=3 multiplication property of equality.
adding the same number to each side of an equation, while two sides remain equal
distributive property of equality
