Question

Indicate which property is illustrated in Step 6.

Answer 1

The property used in step 6 is the additive inverse.

What are algebra properties?

Algebra properties are mathematical properties used to simplify algebraic expressions

In step 6, we have the following expression:

$x + 2 - 2$

The additive property of algebra states that:

$a + (-a) = 0$

i.e. when a number or an expression is added to its inverse, the result is 0.

In $x + 2 - 2$, 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.
