Karissa begins to solve the equation [tex]\frac{1}{2}(x-14)+11=\frac{1}{2} x-(x-4)[/tex]. Her work 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 original equation:

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

Step 1. Expand both sides:

- On the left, distribute [tex]$\frac{1}{2}$[/tex]:

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

Then add [tex]$11$[/tex]:

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

- On the right, distribute the negative sign:

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

Notice that [tex]$\frac{1}{2} x - x$[/tex] simplifies to:

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

So the right side becomes:

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

Step 2. Write the simplified equation:

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

Step 3. Eliminate the constant term by subtracting [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 4. Solve for [tex]$x$[/tex]:

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

[tex]$$
\frac{1}{2}x + \frac{1}{2}x = 0,
$$[/tex]

which simplifies to:

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

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