Hi!

To solve this, first we should group like terms together.

1d - 2d - 10 + 7 = 8 - 10 + 1d - 3d

Simplify

-1d - 10 + 7 = 8 - 10 - 2d

-1d - 3 = -2 - 2d

Add 3 to both sides.

-1d - 3 + 3 = -2 + 3 - 2d

-1d = 1 - 2d

Add 2d to both sides.

-1d + 2d = 1 - 2d + 2d

1d = 1

Divide by 1 on both sides.

1d/1 = 1/1

d = 1

The answer is d = 1

Hope this helps!
