    A little help solving inequalities

    Hi I need some help solving some inequalities involving absolute values...

    says:

    Solve the inequality |2x| + |x-3| < 5 in unions of intervals

    Like i could do it if it was just one term, but the addition of two absolute values is kinda throwing me off. So can anyone help me out on this one? thank you very much in advance.

    consider the following

    |a| = \sqrt{a^2}

    and

     |a|+|b|\geq |a+b|
