Karissa begins to solve the equation:

\[
\frac{1}{2}(x-14) + 11 = \frac{1}{2} x - (x - 4)
\]

Her work is correct and is shown below:

\[
\begin{array}{c}
\frac{1}{2}(x-14) + 11 = \frac{1}{2} x - (x - 4) \\
\frac{1}{2} x - 7 + 11 = \frac{1}{2} x - x + 4 \\
\frac{1}{2} x + 4 = -\frac{1}{2} x + 4
\end{array}
\]

When she subtracts 4 from both sides, \(\frac{1}{2} x = -\frac{1}{2} x\) results. What is the value of \(x\)?

A. \(-1\)

B. \(-\frac{1}{2}\)

C. \(0\)

D. \(\frac{1}{2}\)

Answer :

We begin with the equation
$$
\frac{1}{2}(x-14) + 11 = \frac{1}{2}x - (x-4).
$$

**Step 1. Distribute and simplify each side.**

For the left side:
$$
\frac{1}{2}(x-14) + 11 = \frac{1}{2}x - 7 + 11 = \frac{1}{2}x + 4.
$$

For the right side, distribute the negative sign:
$$
\frac{1}{2}x - (x-4) = \frac{1}{2}x - x + 4 = -\frac{1}{2}x + 4.
$$

So, the equation becomes:
$$
\frac{1}{2}x + 4 = -\frac{1}{2}x + 4.
$$

**Step 2. Eliminate the constant term by subtracting $4$ from both sides.**

Subtracting $4$ from both sides gives:
$$
\frac{1}{2}x + 4 - 4 = -\frac{1}{2}x + 4 - 4 \quad \Longrightarrow \quad \frac{1}{2}x = -\frac{1}{2}x.
$$

**Step 3. Solve for $x$.**

To isolate $x$, add $\frac{1}{2}x$ to both sides:
$$
\frac{1}{2}x + \frac{1}{2}x = -\frac{1}{2}x + \frac{1}{2}x.
$$

Simplify the left side:
$$
\left(\frac{1}{2} + \frac{1}{2}\right)x = 0 \quad \Longrightarrow \quad x = 0.
$$

Thus, the value of $x$ is $\boxed{0}$.
