4x  +  15  ≥  - 9    subtract 15 from both sides

 

4x ≥ - 24         divide both sides by 4

 

x ≥  -6

 

 

8x -  6   ≤  34      add 6  to both sides

 

8x ≤ 40    divide both sides by 8

 

x ≤  5

 

 

 

l 4x  +  3  l   =   3           we have two equations

 

4x  +   3   =    3                                     4x  +  3   =   - 3

 

                                      subtract 3 from both sides

 

4x   =  0                                                4x =  - 6

 

                                       divide both sides by 4

 

  x  = 0                                          x  =  -6/4  =  -3/2
