Give+an+example+of+an+absolute+value+equation+that+has+only+one+solutionSet3

I need to diagree here!! This equation definitely has two solutions!! The inside expression can have a value of 1 or negative 1, since ⎮ 1 ⎮ = 1 and also ⎮ -1 ⎮ = 1. Therefore, your procedure would involve setting 4x - 7 equal to both 1 and -1, and then taking it from there (i.e. solving each of the two equations!) Please fix this!!

⎮ x + 1 ⎮ = 1 -Jeff Lehrer

Sorry Jeff but I disagree -- in your case x+1 could be equal to 1, in which case x = 0, or x+1 could be equal to -1, in which case x = -2. So there are two solutions to your absolute value equation.


 * 5X|=0 -Ryan Sarnacki

Yes. what about ⎮5 + x⎮= 0. Would this also have one solution? What about ⎮5x+1⎮= 0? 1.Yes, both solutions will give x as -5 both times. 2. Yes, both solutions would give x as -1/5. - Nathaniel Tarshish

Nate I think you need to support your answers here!! What would these (multiple) solutions be?
