    Subtract 5 from each side:
    -8|-2n| = -80

    Divide each side by -8
    |-2n| = 10

    Since this is an absolute value equation, we need to setup two equations:

    -2n = 10
    -2n = -10

    Solving for the first one by dividing each side by -2, we get:
    n = -5

    Solving for the second one by dividing each side by -2, we get:
    n = 5
