# Modulus inequality help

## Homework Statement

Solve $$| \frac{x}{2} +3 | > 3-x^2$$
Hence, solve $$| \frac{e^x}{2} -3 | > 3-e^{2x}$$

## The Attempt at a Solution

I've solved the first part. But I have no clue what is the link to the second part?! could there be just typo to the question?? I can't find any links...

Let u=e^x

and it becomes

$$|\frac{u}{2} +3 | > 3-u^2$$

Didn't help.

Anyway I figured the solution already.

should be let $$u= - e^x$$
