1. Solution Using Coins and Pouches: Take away 2 coins, then divide by 4. 1 pouch is equal to 4 coins.
Solution Using Equations: 4x + 2 = 18, 4x = 16, x = 4.
Check Your Answer: 4(4) + 2 = 18, 16 + 2 = 18, 18 = 18.
2. Solution Using Coins and Pouches: Take away 6 coins, then divide by 3. 1 pouch is equal to 2 coins.
Solution Using Equation: 3x + 6 = 12, 3x = 6, x = 2.
Check Your Answer: 3(2) + 6 = 12, 6 + 6 = 12, 12 = 12.
3. Solution Using Coins and Pouches: Take away 3 from coins and 2 pouches. 1 pouch is equal to 6 coins.
Solution Using Equations: 3x + 3 = 2x + 9, x + 3 = 9, x = 6.
Check your Answer: 3(6) + 3 = 2(6) + 9, 18 + 3 = 12 + 9, 21 = 21.
4. Solution using Coins and Pouches: Take away 4 pouches and 15 coins, then divide by 2. 1 pouch is equal to 2 coins.
