Hey! So, like all books, they give you this super simple sample problem, and then some impossible problem on the problem sets.
I know how to do absolute value inequalities. How would one sent up absolute value inequalities when you have absolute values embedded within another absolute value?
Ex 1: lllxl-2l + 3l = 0 (where l is the absolute value sign)
Ex 2: l 2+ lxll + llxl - 2l = 0
