Given the absolute inequality


2|x+3|+1>3

The absolute in equality can be written as:


\begin{gathered} 2|x+3|+1>3 \\ 2|x+3|>3-1 \\ |x+3|>(2)/(2) \\ |x+3|>1 \end{gathered}

Sloving the inequality above, we can split it into two, then we will have;


\begin{gathered} -1>|x+3|\text{and }|x+3|>1 \\ \end{gathered}

Solving the left hand side equation


\begin{gathered} |x+3|<-1 \\ x<-3-1 \\ x<-4 \end{gathered}

To solve for the right hand side we have


\begin{gathered} |x+3|>1 \\ x+3>1 \\ x>1-3 \\ x>-2 \end{gathered}

The graph of the inequality on the number line is shown below

Hence the solution of the inequality is x< -4 and x> -2
