Solve: |2x - 1| = |3x + 5|. write your answers as a list of numbers, separated by commas,
e.g. "23, 19" (but without the quotes).

l 2x - 1 l =  l 3x + 5 l

 

We have two equations

 

2x - 1  =  3x + 5                                                 2x - 1 = - (3x + 5)

 

subtract 5 , 2x from both sides                        2x - 1  = - 3x - 5

 

-6  =  x                                                             add 5, subtract 2x to/from both sides

 

                                                                          4  = - 5x

 

                                                                           divide both sides by -5

 

                                                                              -4/5  =  x 

 

-6, -4/5    ⇒   the answers
