    Remember that the absolute value is the distance so you will have your LHS = 7 or -7

    imagine if the value inside was equal to 7 then abs(7) = 7 now imagine if the value inside was equal to -7 then abs(-7) = 7

    spend a long time thinking about this!!! absolute values will haunt you until you grasp them

    you got it!!! Now just make sure you understand why it is equal to 7 and -7!!! Soon you will see inequalities and you must understand absolute values to succed
