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 :

                     243^3*p-(81)=0 

Step by step solution :

Step  1  :

 1.1     243 = 35

(243)³ = (3⁵)³ = 3¹⁵

Equation at the end of step  1  :

  (315 • p) -  81  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   3¹⁵p - 81  =   81 • (3p - 1) 

Equation at the end of step  3  :

  81 • (3p - 1)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    81   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    3p-1 = 0 

 Add  1  to both sides of the equation : 
                      3p = 1
Divide both sides of the equation by 3:
                     p = 1/3 = 0.333
