    (x - 6)(-2) = 18

    2x = -6

    x = -3

    -2 * (a - 6) = 18

    a - 6 = -9

    a = -3

    Let the number be a.

    -2( a - 6) = 18

    -2a + 12 = 18

    -2a = 18 - 12

    a = 6/-2

    a = - 3

    -2(n - 6) = 18

    Divide both sides by -2

    n - 6 = -9

    add 6 to both sides

    n = -3 <––––
