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. [tex]-\frac{1}{2}[/tex]
C. 0
D. [tex]\frac{1}{2}[/tex]

Answer :

Let's solve the equation step by step:

The given equation is:

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

Step 1: Distribute and simplify both sides.

On the left side, distribute [tex]\(\frac{1}{2}\)[/tex]:

[tex]\[ \frac{1}{2}x - \frac{1}{2} \times 14 + 11 = \frac{1}{2}x - 7 + 11 \][/tex]

The left side simplifies to:

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

On the right side, distribute the negative sign:

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

Step 2: Setting the simplified equations equal to each other, we have:

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

Step 3: Subtract 4 from both sides:

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

Step 4: Add [tex]\(\frac{1}{2}x\)[/tex] to both sides to isolate the variable [tex]\(x\)[/tex]:

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

Combine the terms:

[tex]\[ x = 0 \][/tex]

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