#### Answer

$n=2$ or $n=-2$

#### Work Step by Step

$|-3n|-2=4\longrightarrow$ add 2 to each side
$|-3n|-2+2=4+2\longrightarrow$ add
$|-3n|=6\longrightarrow$ definition of absolute value
$-3n=-6$ or $-3n=6\longrightarrow$ divide each part by -3
$-3n\div-3=-6\div-3$ or $-3n\div-3=6\div-3\longrightarrow$ divide
$n=2$ or $n=-2$
