    -5n - 5n - 5 = 5

    Solve for n in the equation -5n - 5n - 5 = 5

    Step 1: Group the n terms on the left hand side:
    (-5 - 5)n = -10n

    Step 2: Form modified equation
    -10n - 5 = + 5

    Step 3: Group constants:
    We need to group our constants -5 and 5. To do that, we add 5 to both sides
    -10n - 5 + 5 = 5 + 5

    Step 4: Cancel 5 on the left side:
    -10n = 10

    Step 5: Divide each side of the equation by -10
    -10n/-10 = 10/-10

    n = - 1
