Question

WHAT IS ITTTT 3d + 9 = 27

Answer 1

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 2

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
