The property used in step 6 is the additive inverse.
Algebra properties are mathematical properties used to simplify algebraic expressions
In step 6, we have the following expression:
[tex]x + 2 - 2[/tex]
The additive property of algebra states that:
[tex]a + (-a) = 0[/tex]
i.e. when a number or an expression is added to its inverse, the result is 0.
In [tex]x + 2 - 2[/tex], 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.
