#### Answer

The solutions are $x=-17$ or $x=-7.$

#### Work Step by Step

$|x+12|=5\qquad$....write equivalent equations. $x+12=5$ or $x+12=-5\qquad$....solve each equation separately. $x+12=5\qquad$ ...add $-12$ to each side. $x+12-12=5-12\qquad$ ...simplify. $x=-7$ $x+12=-5\qquad$ ...add $-12$ to each side. $x+12-12=-5-12\qquad$ ...simplify. $x=-17$
