The first option: Additive Inverse Property is the right answer
Step-by-step explanation:
Additive inverse can be defined as: " For every number x, there exists a number -x, the sum of both is zero"
Additive Inverse Property:
Additive inverse property states that the sum of a number and it's additive inverse is zero
i.e.
[tex]a + (-a) = 0[/tex]
In the given proof, the same property is used in the step:
[tex]b+a+(-a) = b+[a+(-a)]\\b+a+(-a) = b+0[/tex]
Hence,
The first option: Additive Inverse Property is the right answer
