    {-8,28}

    Step-by-step explanation:

    |10-x|=18

    The absolute value has two solutions, one positive and one negative.

    10-x = 18 and 10-x = - 18

    Subtract 10 from each side

    10-10-x = 18-10 10-10-x=-18-10

    -x = 8 - x = - 28

    Multiply each side by - 1

    x = - 8 x = 28
