Solution - Linear equations with one unknown

Rearrange:

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

                     3-12*d-(32*d+4-d)=0 

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   -1 - 43d  =   -1 • (43d + 1) 

Equation at the end of step  1  :

Step  2  :

Solving a Single Variable Equation :

 2.1      Solve  :    -43d-1 = 0 

 Add  1  to both sides of the equation : 
                      -43d = 1
Multiply both sides of the equation by (-1) :  43d = -1


Divide both sides of the equation by 43:
                     d = -1/43 = -0.023
