    n = - 2

    Step-by-step explanation:

    we apply distributive property:

    -4 (8+5n) = 8

    -4*8 - 4*5n = 8

    we have:

    -32 - 20n = 8

    we add 32 to both sides of the equation:

    -32+32 - 20n = 8 + 32

    we have:

    -20n = 40

    we divide by - 20 to both sides of the equation:

    -20n/-20 = 40/-20

    we have:

    n = - 40/20

    finally we have:

    n = - 2
