4. \( \frac{4}{2} x=6 \)

To solve the equation \( \frac{4}{2} x = 6 \), first simplify \( \frac{4}{2} \) to get \( 2x = 6 \). Next, divide both sides by 2 to isolate \( x \): thus, \( x = 3 \). Simple as pie! In real-world scenarios, understanding how to manipulate equations can help you budget better! If you're looking to divide a budget equally among friends or calculate how much each person owes after dinner, algebra helps you find those answers quickly and accurately.
