To solve the equation 3(x + 6) - 27 = 27, we can follow these steps:

1. Distribute the 3 to the terms inside the parentheses:
3x + 18 - 27 = 27

2. Combine like terms:
3x - 9 = 27

3. Add 9 to both sides of the equation to isolate the variable term:
3x = 36

4. Divide both sides of the equation by 3 to solve for x:
x = 12

Therefore, the solution to the equation 3(x + 6) - 27 = 27 is x = 12.
