j) \( \frac{12}{x}=3 \)

To solve the equation \( \frac{12}{x} = 3 \), start by multiplying both sides by \( x \) to eliminate the fraction, giving you \( 12 = 3x \). Next, divide both sides by 3 to isolate \( x \), which leads to \( x = 4 \). Voilà! You’ve found that \( x \) equals 4! Now, let’s think about how this simple algebraic skill shows up in real life. Whether you're budgeting, adjusting a recipe, or even determining the right dosage of medicine, being able to solve equations like this can help you find the missing pieces to many everyday puzzles in a quick and efficient manner!
