We should end up with two solutions, here, CalculatorofDoom......that's OK....I gave you 5 points for a good effort........

 

2|3x - 4|+ 7 = 29       subtract 7 from both sides

 

2  l 3x - 4 l  = 22       divide both sides by 2

 

l 3x - 4 l  = 11   

 

We have two equations

 

3x - 4  = 11                       and           3x - 4 =  - 11

 

                      add 4 to both sides

 

3x   = 15                                           3x  = - 7

                  

                     divide both sides by 3

 

x = 5                           and              x = -7 /3
