$x=-5$ or $x=1$
$3|x+2|+4=13\longrightarrow$ subtract 4 from each side $3|x+2|+4-4=13-4\longrightarrow$ subtract $3|x+2|=9\longrightarrow$ divide each side by 3 $3|x+2|\div3=9\div3\longrightarrow$ divide $|x+2|=3\longrightarrow$ definition of absolute value $x+2=-3$ or $x+2=3\longrightarrow$ subtract 2 from each part $x+2-2=-3-2$ or $x+2-2=3-2\longrightarrow$ subtract $x=-5$ or $x=1$
