Divide everything in the equation by 3 giving you: 
$$2x+6=4$$    then put the equation equal to 4 & -4

-4=2x+6      4=2x+6

solve for x...you'll have two answers

-3I2x + 6I = -12
I2x + 6I = -12/-3 
-(2x + 6) = 4                          &    2x + 6 = 4
-2x - 6 = 4                             & 2x = 4-6
-2x = 4 + 6                            & 2x = -2
-2x = 10                                 & x = -2/2

x = 10/-2 = -5      & -1
