solve each inequality, graph its solution set and write the solution set in interval notation. -1/2|x+7| = 6 write in interval notation

OpenStudy (campbell_st):

this isn't an inequality... its an equation

if you multiply both sides by -1/2 you have | x + 7| = -3 which is interesting as absolute value functions are always positive.... so maybe a typo or 2
