🌍 Where you'd use this: Anytime someone says 'figure out X if you know Y' — you're doing algebra.

🤯 Fun fact: 🤯 The letter 'x' is used for 'unknown' because of an Arabic word that French printers couldn't easily print.

🏆 Try this week: Find one real-life situation today that uses an unknown. Write the equation for it.
