It's like your final ex, save there's a number attached to the back end.

somthing like this...... 7 http://www.mathhelpforum.com/math-he...fe8dc286-1.gif

Sorry about the lack of detail. Just trying to speed things up.. Typing wise, anyhow. - September 5th 2008, 02:20 PMJhevon

In that case, do NOT multiply the 7 with the expression 3x - 1. That'll change the absolute value! Instead, divide 7 on both sides, and then proceed.

|3x - 1| = 2/7

Now proceed...

I hope that helps. :)

Much thanks. Couldn't really remember whether to subtract or divide.....

You can't subtract because it's . You must divide the 7 on both sides.
