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 :

                     7*(d-1)-(6*d)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  7 • (d - 1) -  6d  = 0 

Step  2  :

Equation at the end of step  2  :

  d - 7  = 0 

Step  3  :

Solving a Single Variable Equation :

 3.1      Solve  :    d-7 = 0 

 Add  7  to both sides of the equation : 
                      d = 7
