Question

I'm so confused on what I did wrong ​

Answer 1

`r < 15.5`

Explanation:

Step 1: Add 4.5 to both sides

`r - 4.5 < 11`

`r - 4.5 + 4.5 < 11 + 4.5`

`r < 15.5`

Answer:
`r < 15.5`

I don't really know what you did wrong but it seems like you added 45 to 11 instead of adding 4.5 to 11.

Hope this helps! Let me know if you have any questions
