okay so I need to have this problem solved and I'm having a really hard time with it :[
3|2x-1|+3=1
-------
5
i need to solve for x

its 2x-1 over 5, not 1/5
2006-11-26 13:58:15 · update #1
I already answered this in the other thread. Theres no solution: |2x-1| >= 0, so the left hand side is >= 0 + 3 = 3.
Note that I'm not telling you that you did something wrong - 'no solution' is a perfectly legal answer to 'solve for x'.

The bars around (2x-1)/5 signify that the equation is an absolute value. Subsequently, a negative number cannot be used as it converts to a positive number in this situation. If you move +3 to the right, you get 3|(2x-1 over 5)|=-2
This is impossible to solve for since you can't multiply 3 by a negative number.

Is the whole left side over 5? If so, here's how.
Multiply both sides by 5.
3|2x+1|+3=5
Subtract 3 from both sides.
3|2x+1|=2
Divide both sides by 3.
|2x+1|=2/3
Then solve the 2 equations...2x+1=2/3 and 2x+1=-2/3.

3 (2x +1) + 3 = 1
6x +3 +3 =1
6x +6 =1
6x= -5
x= -5/6
I hope this is right...I haven't done absolute value in a while

3/5|2x-1| + 3=1
3/5|2x-1|=-2
which is not possible therefore no answer
