Let's solve the equation step by step:
Given the equation:
\[ 2x - 4x - 3 = -27 \]
First, combine the like terms on the left side:
\[ -2x - 3 = -27 \]
Next, add 3 to both sides to isolate the term involving \(x\):
\[ -2x = -27 + 3 \]
This simplifies to:
\[ -2x = -24 \]
Now, divide both sides by -2 to solve for \(x\):
\[ x = \frac{-24}{-2} \]
This simplifies to:
\[ x = 12 \]
Thus, the solution is:
D. x = 12
