2. Which of the following contextual situations can be represented by the one step equation \( y+5=17 \) Jeff has 17 pokemon cards after buying 5 more. How many pokemon cards did he have before buying more?

When we look at Jeff's situation, it's a classic "before and after" problem in mathematics. Jeff ends up with 17 Pokémon cards after he purchases 5 more, which means if he subtracts the 5 cards he bought from his total, we can easily find out how many he had initially! This type of problem helps students understand how equations can model real-life scenarios. To solve for \( y \) in the equation \( y + 5 = 17 \), simply subtract 5 from both sides. This gives you \( y = 17 - 5 \), which simplifies to \( y = 12 \). So, Jeff had 12 Pokémon cards before his purchase! This process not only strengthens algebra skills but also enhances logical thinking as we work through such problems.
