Solution - Absolute value equations

Absolute Value Equation entered :

      |2x|=17 

Step by step solution :

Step  1  :

Rearrange this Absolute Value Equation

Absolute value equalitiy entered
      |2x| = 17 

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 |2x|

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

For the Positive case we'll use (2x) 

Step  3  :

Solve the Negative Case

      -(2x) = 17 

     Multiply
      -2x = 17 

     Divide both sides by 2
      -x = (17/2) 

     Multiply both sides by (-1)
      x = -(17/2) 
     Which is the solution for the Negative Case

Step  4  :

Solve the Positive Case

      (2x) = 17 

     Divide both sides by 2
      x = (17/2) 

     Which is the solution for the Positive Case

Step  5  :

Wrap up the solution

 x=-17/2
 x=17/2
