The general procedure for solving inequation containing modulus functions is to split the domain into subintervals and solve the various cases. But there are certain structures of equations which can be solved by a different approach.
For example:
i) The inequation 
has no solution.
ii) Solving the inequaiton 
is equivalent to solving the equations 
iii) Solving the inequation 
is equivalent to solving the equations 
iv) Solving the inequation
