Answer: The correct option is
(7) Identity - addition.
Step-by-step explanation: We are given to select the property that allows the left member of the equation to be changed to the right member.
8 + 0 = 8.
We now that
if a is a real number, then the equation a + 0 = a is the additive identity.
Putting a = 8, we get
[tex]8+0=8.[/tex]
Thus, the required property is additive identity.
Option (7) is CORRECT.
