The property used in step 6 is the additive inverse.
<h3>What are algebra properties?</h3>Algebra properties are mathematical properties used to simplify algebraic expressions
In step 6, we have the following expression:
The additive property of algebra states that:
i.e. when a number or an expression is added to its inverse, the result is 0.
In , we have:
2 and -2
2 and -2 are inverses or opposites.
So, when they are added; the result is 0
Hence, the property used in step 6 is the additive inverse.
