Let's clear that up! 🎉 **Step 1:** We said Group 1 is $(x - 4)$, so it has 4 toys: 🧸 🧸 🧸 🧸 (4 toys) **Step 2:** Group 2 is $(x + 4)$, so it has 4 toys plus the $x$ part. **Step 3:** The $x$ is like a special toy that stands for something bigger. The +4 means 4 more toys. **Step 4:** So Group 2 has $x$ (one big toy) and 4 small toys: 🧸 🧸 🧸 🧸 **Step 5:** We can't count $x$ as 1 toy, it's a letter that means something else. So Group 2 is $x + 4$ toys. Imagine:

Group 1 (x - 4):
❌ 🧸 🧸 🧸 🧸
(4 toys missing from x)

➕

Group 2 (x + 4):
🅇 🧸 🧸 🧸 🧸
(x plus 4 toys)

Great question! The $x$ is like a mystery toy, not just a number. So we show it with a special letter emoji 🅇. 🌟
