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 :

                     2^3*n-(4)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (23 • n) -  4  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   8n - 4  =   4 • (2n - 1) 

Equation at the end of step  3  :

  4 • (2n - 1)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    4   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    2n-1 = 0 

 Add  1  to both sides of the equation : 
                      2n = 1
Divide both sides of the equation by 2:
                     n = 1/2 = 0.500
