Let x be the actual voltage.


The absolute value inequality to describe this situation is

    |x - 110| <= 5  volts.


The solution to this inequality is, step by step,

    -5 <= x - 110 < 5,

    -5 + 110 <= x <= 5 + 110,

    105 <= x <= 115  volts.    ANSWER


Thus you get the the equation and its solution.
