3. Solve for x . \[ \frac{1}{2} x=8 \]

To solve for x in the equation \( \frac{1}{2} x = 8 \), start by eliminating the fraction. You can do this by multiplying both sides of the equation by 2. So, \( 2 \cdot \frac{1}{2} x = 2 \cdot 8 \), which simplifies to \( x = 16 \). Voilà! x is 16! Now, using this equation in real life, let's say you're splitting a pizza between two people, and each person gets half of a pizza. If you find out that half of the pizza represents 8 slices, you can easily determine that the whole pizza has 16 slices. See? Math helps resolve delicious pizza dilemmas!
