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 :

                -4*(3-6*d)-(9*(2*d-2))=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   2d - 2  =   2 • (d - 1) 

Equation at the end of step  2  :

  (0 -  (4 • (3 - 6d))) -  18 • (d - 1)  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   3 - 6d  =   -3 • (2d - 1) 

Equation at the end of step  4  :

  (0 -  -12 • (2d - 1)) -  18 • (d - 1)  = 0 

Step  5  :

Step  6  :

Pulling out like terms :

 6.1     Pull out like factors :

   6d + 6  =   6 • (d + 1) 

Equation at the end of step  6  :

  6 • (d + 1)  = 0 

Step  7  :

Equations which are never true :

 7.1      Solve :    6   =  0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation :

 7.2      Solve  :    d+1 = 0 

 Subtract  1  from both sides of the equation : 
                      d = -1
