1 and 3 are proportional.
2 and 4 not proportional.

4(d-8)-5 = 9(d+2)+1

Assuming you're looking for d:

Use Distributive Property for both sides
4d-32-5 = 9d+18+1

Combine like terms
4d-37 = 9d+19

Take all d's to one side & numbers to other
-37-19 = 9d-4d

Simplify
-56 = 5d

Divide both sides by 5
d = -56/5
