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 :

                     128^3*x-(8)=0 

Step by step solution :

Step  1  :

 1.1     128 = 27

(128)³ = (2⁷)³ = 2²¹

Equation at the end of step  1  :

  (221 • x) -  8  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   2²¹x - 8  =   8 • (16x - 1) 

Equation at the end of step  3  :

  8 • (16x - 1)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    8   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    16x-1 = 0 

 Add  1  to both sides of the equation : 
                      16x = 1
Divide both sides of the equation by 16:
                     x = 1/16 = 0.062
