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*(2*n-4)-((4*n+2)+7)=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   2n - 4  =   2 • (n - 2) 

Equation at the end of step  2  :

  18 • (n - 2) -  (4n + 9)  = 0 

Step  3  :

Equation at the end of step  3  :

  14n - 45  = 0 

Step  4  :

Solving a Single Variable Equation :

 4.1      Solve  :    14n-45 = 0 

 Add  45  to both sides of the equation : 
                      14n = 45
Divide both sides of the equation by 14:
                     n = 45/14 = 3.214
