absolute value

[mathgeek]

I am confused about how to do absolute value. I never learned how to do it in middle school, but I know it will come in handy on the SAT and ACT. Can anyone give me a step by step walk through of how to do this.


What are the possible values of x in |12-4x|=2?

Any help would be greatly appreciated.

Thanks.
