Answer:

-10 -2d+7=8-10-3d

-2d + 7 =8 -3d

-2d + 7 =3d = 8

-2d + 3d = 8-7

d=8-7

d=1

Answer:


d = 1

Explanation:

Step 1: Combine like terms


d - 10 - 2d + 7 = 8 + d - 10 - 3d


(d - 2d) + (-10 + 7) = (8 - 10) + (d - 3d)


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

Step 2: Add 2d to both sides


-d + 2d - 3 = -2 - 2d + 2d


d - 3 = -2

Step 3: Add 3 to both sides


d - 3 + 3 = -2 + 3


d = 1

Answer:
d = 1
