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 :

                9*d-3*d+2*d-7*d+2*d-(18)=0 

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   3d - 18  =   3 • (d - 6) 

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

 2.1      Solve :    3   =  0

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

Solving a Single Variable Equation :

 2.2      Solve  :    d-6 = 0 

 Add  6  to both sides of the equation : 
                      d = 6
