for ex: 
 

\(|2x+2|≥ 2 \)

 

\(|2x+1|<2\)

 

How do you write these in solution set form?? I am really confused and have an exam coming up! 

All help is appreciated!! 
thank you!

\(|2x+2|\geq 2\\~\\ 2x+2\geq 2 \Rightarrow x\geq 1\\ 2x+2 \leq -2 \Rightarrow x \leq -2\\~\\ S = \{x : x \in (-\infty, -2] \cup [1,\infty)\}\)

 

I leave the second one to you.
