To subtract \( (3g - 4) - 2(3g + 4) \), follow these steps:
1. Distribute the \( -2 \) across the expression \( (3g + 4) \):
\[
-2(3g + 4) = -2 \cdot 3g - 2 \cdot 4 = -6g - 8
\]
2. Now substitute this back into the original expression:
\[
(3g - 4) - (6g + 8) = 3g - 4 - 6g - 8
\]
3. Combine like terms:
\[
(3g - 6g) + (-4 - 8) = -3g - 12
\]
So, the final answer is:
\[
-3g - 12
\]
