(1): Dot was discarded near "8.".

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                     -12*x-7-(18)=0 

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   -12x - 25  =   -1 • (12x + 25) 

Equation at the end of step  1  :

Step  2  :

Solving a Single Variable Equation :

 2.1      Solve  :    -12x-25 = 0 

 Add  25  to both sides of the equation : 
                      -12x = 25
Multiply both sides of the equation by (-1) :  12x = -25


Divide both sides of the equation by 12:
                     x = -25/12 = -2.083
