    When we have absolute values, we get two solutions, so we have \[-(2x-8)<4 ~~~~\text{and}~~~~(2x-8)<4\]

    haha, \[-(2x-8)<4 \] is also the same as \[2x-8>-4\]

    when you divide by a negative we usually switch the sign

    |dw:1444559321606:dw| this is essentially what you need to know when you see absolute values

    Yes, your answer looks good! \[(2x-8)<4 \] and we have \[-(2x-8)<4 \implies 2x-8>-4\] remember when we divide by a negative the sign flips.
