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


-3d-6+(-4)=5\\-3d-10=-5\\-3d=5\\3d=-5\\d=-(5)/(3)

Answer:

d=−1

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
