You want to get x on only one side. By subtracting x from both sides you isolate it although I would add 4x to both sides to avoid negative inequalities giving
i am trying to learn how to slove linear inequalities and im stuck!
In problems like 6 -4x < x +1 i know the text book tells me to use -x to both sides.
Ok.. this brings me to my question. when doing these im lost on which number to pick and subtract!! why not the 6 or the 1. please help.
When i sit down and get ready to work the problem.. im stuck at the first step at.. do i add and sub the 6 through out the problem or or 1 or -4x.. where do i start?
