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-4*d-9*d+9-(13)=0 

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   -22d - 4  =   -2 • (11d + 2) 

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

 2.1      Solve :    -2   =  0

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

Solving a Single Variable Equation :

 2.2      Solve  :    11d+2 = 0 

 Subtract  2  from both sides of the equation : 
                      11d = -2
Divide both sides of the equation by 11:
                     d = -2/11 = -0.182
