    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

    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!
