I hope this is clear! When you want to remove a modulus, you must consider the condition when the value within the modulus is negative & when it is positive.
For example:
|x + 3| = (x + 3) when x >= -3
|x + 3| = -(x + 3) when x < -3
I hope this makes you understand the topic of modulus better! It can be tricky at first but you'll get the hang of it :)
