    Divide both sides by - 5.5.

    simplify - 12.1/-5.5 to 2.2.

    add 2 to both sides

    simplify 2.2 + 2 to 4.2

    Answer: d = 4.2

    -5.5 (d-2) = - 12.1

    Divide both sides by - 5.5

    d - 2 = - 12.1 / - 5.5

    Add 2 to both sides

    d = (12.1 / 5.5) + 2

    d = 2.2 + 2

    d = 4.2
