To solve the equation \( \frac{1}{2}(8x - 6) = x - 12 \), we will follow these steps:
- Distribute \( \frac{1}{2} \) to both terms inside the parentheses:
\[ \frac{1}{2} \cdot 8x - \frac{1}{2} \cdot 6 = 4x - 3 \]
- So, the equation now looks like this:
\[ 4x - 3 = x - 12 \]
- Next, we will isolate \( x \). First, subtract \( x \) from both sides:
\[ 4x - x - 3 = -12 \]
This simplifies to:
\[ 3x - 3 = -12 \]
- Now, add \( 3 \) to both sides:
\[ 3x = -12 + 3 \]
This simplifies to:
\[ 3x = -9 \]
- Finally, divide both sides by \( 3 \):
\[ x = \frac{-9}{3} = -3 \]
Thus, the value of \( x \) is
\[ \boxed{-3} \]
