Happy Sunday!
Let's say I have this question...
|x+5|=2
Why do I see most people solve this type of question in this way...
First case --> x+5=2
Second case --> x+5=-2
Instead of putting the negative sign on what was inside the absolute value bars (and distributing the negative)?
First case --> x+5=2
Second case --> -(x+5)=2
Many thanks

If you are getting the inequalities correct using your own method, there is no need to copy someone else. Somethings may just come down to preference, for example.

Hi woohoo921,
In your example, the two options to 'translate' that Absolute Value are mathematically equivalent, so you can use either option. That having been said, the more common presentation is likely to keep a 'positive variable' in the equation (since having a "-X" gives you one more 'step'/factor to have to work through).
