Solution - Absolute value equations

Absolute Value Equation entered :

      |3x-2|=5 

Step by step solution :

Step  1  :

Rearrange this Absolute Value Equation

Absolute value equalitiy entered
      |3x-2| = 5 

Step  2  :

Clear the Absolute Value Bars

Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is |3x-2|

 For the Negative case we'll use -(3x-2) 

For the Positive case we'll use (3x-2) 

Step  3  :

Solve the Negative Case

      -(3x-2) = 5 

     Multiply
      -3x+2 = 5 

     Rearrange and Add up
      -3x = 3 

     Divide both sides by 3
      -x = 1 

     Multiply both sides by (-1)
      x = -1 
     Which is the solution for the Negative Case

Step  4  :

Solve the Positive Case

      (3x-2) = 5 

     Rearrange and Add up
      3x = 7 

     Divide both sides by 3
      x = (7/3) 

     Which is the solution for the Positive Case

Step  5  :

Wrap up the solution

 x=-1
 x=7/3
