Karissa begins to solve the equation:

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

Her work is correct and is shown below:

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

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

A. [tex]\(-1\)[/tex]
B. [tex]\(-\frac{1}{2}\)[/tex]
C. [tex]\(0\)[/tex]
D. [tex]\(\frac{1}{2}\)[/tex]

Answer :

We start with the equation

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

Step 1. Expand both sides

Expand the left-hand side:

[tex]$$
\frac{1}{2}(x-14) + 11 = \frac{1}{2}x - 7 + 11 = \frac{1}{2}x + 4.
$$[/tex]

Expand the right-hand side:

[tex]$$
\frac{1}{2}x - (x-4) = \frac{1}{2}x - x + 4 = -\frac{1}{2}x + 4.
$$[/tex]

So the equation becomes

[tex]$$
\frac{1}{2}x + 4 = -\frac{1}{2}x + 4.
$$[/tex]

Step 2. Eliminate the constant

Subtract [tex]$4$[/tex] from both sides:

[tex]$$
\frac{1}{2}x + 4 - 4 = -\frac{1}{2}x + 4 - 4,
$$[/tex]

which simplifies to

[tex]$$
\frac{1}{2}x = -\frac{1}{2}x.
$$[/tex]

Step 3. Solve for [tex]$x$[/tex]

Add [tex]$\frac{1}{2}x$[/tex] to both sides to combine like terms:

[tex]$$
\frac{1}{2}x + \frac{1}{2}x = -\frac{1}{2}x + \frac{1}{2}x.
$$[/tex]

This gives

[tex]$$
x = 0.
$$[/tex]

Thus, the value of [tex]$x$[/tex] is [tex]$\boxed{0}$[/tex].
