**Here’s my logical proof why I think there’s an error in this.**

Start with the second line,

🧤 + 🧤 + 🥾 = 42

2 🧤 + 🥾 = 42

🥾 = 42 - 2 🧤

Therefore

42 - 2 🧤

= An even number subtracted by an even number

= an even number

Therefore

🥾 = an even number

Therefore

The first line below cannot equal an odd number.
