    Answer:

    d=−1

    Step-by-step explanation:

    −3(d−2)−4=5

    Step 1: Simplify both sides of the equation.

    −3(d−2)−4=5

    (−3)(d)+(−3)(−2)+−4=5(Distribute)

    −3d+6+−4=5

    (−3d)+(6+−4)=5(Combine Like Terms)

    −3d+2=5

    −3d+2=5

    Step 2: Subtract 2 from both sides.

    −3d+2−2=5−2

    −3d=3

    Step 3: Divide both sides by -3.

    −3d

    −3

    =

    3

    −3

    d=−1

    -3(d+(-2))+(-4)=5

    -3d-6+(-4)=5\\-3d-10=-5\\-3d=5\\3d=-5\\d=-\frac{5}{3}
