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 :

To solve the equation [tex]\(\frac{1}{2}(x-14) + 11 = \frac{1}{2}x - (x-4)\)[/tex] step-by-step, let's break it down:

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

Distribute [tex]\(\frac{1}{2}\)[/tex] to both [tex]\(x\)[/tex] and [tex]\(-14\)[/tex]:
[tex]\[
\frac{1}{2}x - \frac{1}{2} \cdot 14 + 11 = \frac{1}{2}x - (x - 4)
\][/tex]
[tex]\[
\frac{1}{2}x - 7 + 11 = \frac{1}{2}x - x + 4
\][/tex]

2. Simplify both sides of the equation:
Combine like terms:
[tex]\[
\frac{1}{2}x + 4 = \frac{1}{2}x - x + 4
\][/tex]

3. Isolate the variable [tex]\(x\)[/tex]:
First, subtract 4 from both sides to get:
[tex]\[
\frac{1}{2}x = \frac{1}{2}x - x
\][/tex]

Simplify the right side:
[tex]\[
\frac{1}{2}x = -\frac{1}{2}x
\][/tex]

4. Combine like terms to solve for [tex]\(x\)[/tex]:
Add [tex]\(\frac{1}{2}x\)[/tex] to both sides to combine the [tex]\(x\)[/tex] terms on one side:
[tex]\[
\frac{1}{2}x + \frac{1}{2}x = 0
\][/tex]
[tex]\[
x = 0
\][/tex]

Therefore, the value of [tex]\(x\)[/tex] is [tex]\(\boxed{0}\)[/tex].
