Answer:

d=-8

Explanation:

1) Use the Distributive property on the left side of the equation:

3d-24-5=9(d+2)+1

2) Use the Distributive property on the right side of the equation:

3d-24-5=9d+18+1

3) Combine alike terms:

3d-29=9d+19

4) add a 29 to both sides:

3d=9d+48

5) Subtract a 9d from both sides:

-6d=48

6) Divide both sides by -6:

d=-8
