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 :

                     81^2*p-(27)=0 

Step by step solution :

Step  1  :

 1.1     81 = 34

(81)² = (3⁴)² = 3⁸

Equation at the end of step  1  :

  (38 • p) -  27  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   6561p - 27  =   27 • (243p - 1) 

Equation at the end of step  3  :

  27 • (243p - 1)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    27   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    243p-1 = 0 

 Add  1  to both sides of the equation : 
                      243p = 1
Divide both sides of the equation by 243:
                     p = 1/243 = 0.004
