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 :

                     13*d+8-(-1)=0 

Step by step solution :

Step  1  :

Solving a Single Variable Equation :

 1.1      Solve  :    13d+9 = 0 

 Subtract  9  from both sides of the equation : 
                      13d = -9
Divide both sides of the equation by 13:
                     d = -9/13 = -0.692
