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 :

                     125^2*n-(625)=0 

Step by step solution :

Step  1  :

 1.1     125 = 53

(125)² = (5³)² = 5⁶

Equation at the end of step  1  :

  (56 • n) -  625  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   5⁶n - 625  =   125 • (n - 5) 

Equation at the end of step  3  :

  125 • (n - 5)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    125   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    n-5 = 0 

 Add  5  to both sides of the equation : 
                      n = 5
