To solve the equation 12 + 9w = w - 15, first, subtract w from both sides to isolate the variable on one side of the equation. Then, add 15 to both sides to move the constant term to the other side. Finally, combine like terms and solve for w.

Here are the steps:

12 + 9w = w - 15

Subtract w from both sides:

12 + 8w = -15

Add 15 to both sides:

12 + 8w + 15 = 0

Combine like terms:

27 + 8w = 0

Subtract 27 from both sides:

8w = -27

Divide both sides by 8:

w = -27/8
