1. Step-by-step explanation:

   For a number

   a

   , it’s multiplicative inverse

   b

   is such that

   a

   ⋅

   b

   =

   1

   which is the multiplicative identity.

   For a number

   a

   , it’s additive inverse

   c

   would be such that

   a

   +

   c

   =

   0

   where

   0

   is additive identity.

   Thus, for

   a

   =

   −

   8

   It’s additive inverse be

   c

   .

   Then

   −

   8

   +

   c

   =

   0

   Now, adding

   8

   to both sides,

   c

   =

   8

   .

   Let the multiplicative inverse be

   b

   .

   Then

   a

   ⋅

   b

   =

   1

   ⇒

   −

   8

   ⋅

   b

   =

   1

   Multiplying both sides with

   −

   1

   8

   b

   =

   −

   1

   8

2. Step-by-step explanation:

   -8+a= -3

   if we subtract-8 and -3 we get -5

   so….

   -8+-5=-3

   and when we do the value of a in additive inverse we get 5

   so the final answer is

   -8+5=-3

   hope this help you!
