\( x + 4 = 12 , x = \square \)

To solve the equation \( x + 4 = 12 \), you simply subtract 4 from both sides. This gives you \( x = 12 - 4 \), which simplifies to \( x = 8 \). Voilà! The mystery of \( x \) is solved: it's 8! You can also represent this equation visually on a number line. Imagine placing a point at 4 and then moving 8 units to the right to land at 12. It’s a great way to understand the concept of equations as finding the right position on a number line!
