The reflexive property of relations is not the same as the addition property of equality.
A # that is + and is= ex 5=5
When the coefficient of that variable, in which you want to eliminate, is negative.
Addition Property of Equality (APOE)
The addition of the opposite, to both sides of the equation. keep it equal
The reflexive property of relations is not the same as the addition property of equality.
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.
The addition property of equality states that if you add the same number to both sides of an equation, then the sides remain even. This means that the equation remains to be true.
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.
When the coefficient of that variable, in which you want to eliminate, is negative.

The addition of the opposite, to both sides of the equation. keep it equal
The subtraction of equality.
6z+28=12z+10 6z-12z=10-28 addition property of equality. -6z=-18 simplification z=3 multiplication property of equality.
