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 :

                     4^7*x-(250)=0 

Step by step solution :

Step  1  :

 1.1     4 = 22

(4)⁷ = (2²)⁷ = 2¹⁴

Equation at the end of step  1  :

  (214 • x) -  250  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   2¹⁴x - 250  =   2 • (2x - 125) 

Equation at the end of step  3  :

  2 • (2x - 125)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    2   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    2x-125 = 0 

 Add  125  to both sides of the equation : 
                      2x = 125
Divide both sides of the equation by 2:
                     x = 125/2 = 62.500
