    B - 4

    Step-by-step explanation:

    -1.5 (4 - r) = - 12

    Distribute - 1.5.

    -6 + 1.5r = - 12

    Add 6 to both sides.

    1.5r = - 6

    Divide both sides by 1.5.

    r = - 4

    Your answer is - 4.

    r = - 4

    Step-by-step explanation:

    -1.5 (4-r) = -12

    Divide each side by - 1.5

    -1.5 / - 1.5 * (4-r) = -12 / - 1.5

    (4-r) = 8

    Subtract 4 from each side

    4-r-4 = 8-4

    -r = 4

    Divide each side by - 1

    -r/-1 = 4/-1

    r = - 4
