Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{d = 6}}}}}

Step-by-step explanation:

\sf{3d + 9 = 27}

Move 9 to right hand side and change its sign

\dashrightarrow{ \sf{3d = 27 - 9}}

Subtract 9 from 27

\dashrightarrow{ \sf{3d = 18}}

Divide both sides by 3

\dashrightarrow{ \sf{ \frac{3d}{3}  =  \frac{18}{3}}}

Calculate

\dashrightarrow{ \sf{d = 6}}

Hope I helped!

Best regards! :D

Answer:

d = 6

Step-by-step explanation:

3d + 9 = 27

Subtract 9 from each side

3d + 9-9 = 27-9

3d = 18

Divide each side by 3

3d/3 = 18/3

d = 6
