Let's solve the equation step by step.
The equation given is:
\[ 6(2x - 3) + 4 = 16 - (-18) \]
First, simplify the right side:
\[ 16 - (-18) = 16 + 18 = 34 \]
Now the equation is:
\[ 6(2x - 3) + 4 = 34 \]
Next, subtract 4 from both sides:
\[ 6(2x - 3) = 34 - 4 \] \[ 6(2x - 3) = 30 \]
Now, divide both sides by 6:
\[ 2x - 3 = \frac{30}{6} \] \[ 2x - 3 = 5 \]
Next, add 3 to both sides:
\[ 2x = 5 + 3 \] \[ 2x = 8 \]
Now, divide by 2:
\[ x = \frac{8}{2} \] \[ x = 4 \]
Thus, the solution is:
\[ \boxed{4} \]
So the answer is A) \( x = 4 \).
