    x = - 15 thus c: is your answer

    Step-by-step explanation:

    Solve for x:

    10 = (-2 x) / 3

    10 = (-2 x) / 3 is equivalent to (-2 x) / 3 = 10:

    (-2 x) / 3 = 10

    Multiply both sides of (-2 x) / 3 = 10 by - 3/2:

    (-3 (-2) x) / (2*3) = (-3) / 2*10

    (-3) / 2 * (-2) / 3 = (-3 (-2)) / (2*3):

    (-3 (-2)) / (2*3) x = (-3) / 2*10

    (-3) / 2*10 = (-3*10) / 2:

    (-3 (-2) x) / (2*3) = (-3*10) / 2

    (-3) / 3 = (3 (-1)) / 3 = - 1:

    (-2-1 x) / 2 = (-3*10) / 2

    (-2) / 2 = (2 (-1)) / 2 = - 1:

    --1 x = (-3*10) / 2

    (-1) ^2 = 1:

    x = (-3*10) / 2

    10/2 = (2*5) / 2 = 5:

    x = - 35

    -3*5 = - 15:

    Answer: x = - 15
