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. -1
B. -\frac{1}{2}
C. 0
D. \frac{1}{2}

Answer :

Sure! Let's solve the equation step-by-step:

The equation Karissa is working with is:
[tex]\[
\frac{1}{2}(x - 14) + 11 = \frac{1}{2}x - (x - 4)
\][/tex]

### Step 1: Simplify Each Side

First, simplify both sides of the equation.

On the left side:
[tex]\[
\frac{1}{2}(x - 14) + 11 = \frac{1}{2}x - \frac{1}{2} \cdot 14 + 11 = \frac{1}{2}x - 7 + 11 = \frac{1}{2}x + 4
\][/tex]

On the right side:
[tex]\[
\frac{1}{2}x - (x - 4) = \frac{1}{2}x - x + 4
= -\frac{1}{2}x + 4
\][/tex]

### Step 2: Set the Simplified Equation

Now, set the simplified expressions equal to each other:
[tex]\[
\frac{1}{2}x + 4 = -\frac{1}{2}x + 4
\][/tex]

### Step 3: Isolate [tex]\(x\)[/tex]

Subtract 4 from both sides:
[tex]\[
\frac{1}{2}x = -\frac{1}{2}x
\][/tex]

Next, add [tex]\(\frac{1}{2}x\)[/tex] to both sides to get all the [tex]\(x\)[/tex] terms on one side:
[tex]\[
\frac{1}{2}x + \frac{1}{2}x = 0
\][/tex]

Combine like terms:
[tex]\[
x = 0
\][/tex]

### Conclusion

The value of [tex]\(x\)[/tex] is 0.
