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*n-(30)=0 

Step by step solution :

Step  1  :

Solving a Single Variable Equation :

 1.1      Solve  :    7n-30 = 0 

 Add  30  to both sides of the equation : 
                      7n = 30
Divide both sides of the equation by 7:
                     n = 30/7 = 4.286
