Question 1044837: --------------------------------------------------------------------------------
Question 1044834: O.k. tell my where I'm going wrong here: |2x-3|+4=2-----> 2x-3+4=2-4----->2x-3=-2---->2x-3+3=-2+3---->2x=1---->2x/2=1/2----->x=.50
and if you ad a negative to =2--->=-2---->answer is x=-1.50
but both these answers are with in the hash marks, with another number and
which you just ignore the polarity and consider it positive?
as you can see I'm in a world of confusion here! ha
how do I make sense of all this
thanks

abs%282x-3%29%2B4=2
Solve first just for the absolute value, if it can be isolated.
abs%282x-3%29%2B4-4=2-4
abs%282x-3%29=-2
THIS is impossible.
NO SOLUTION.
An absolute value is not a signed number, and can never be considered negative. An absolute value itself is never less than zero.
The expression inside the absolute value machine may be positive, or zero, or negative. The absolute value machine, once it contains a number, will only produce either a non-signed, ASSUMED POSITIVE value, OR zero.


O.K. Just to be sure. You're saying the VERY INSTANT a Negative occurs on the other side of the equal sign, stop right there and move on (adding a 0 with a / over it)?
thanks

Just what I said: An absolute value is NEVER a negative quantity.

What is the absolute value equated to? Is it a negative value? Then this is impossible. Is it equated to zero or a positive value? Then the variable inside the absolute value function may have a solution.
