Saving for the game

A game costs $11. You already have $3 saved, and you earn the same amount $x each week for 2 weeks. So 2x + 3 = 11. How much do you need to earn per week? This is a two-step equation — and it's the bridge from arithmetic into real algebra.

Two operations were done to x: ×2, then +3. Undo both.
