Solution - Linear equations with one unknown

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "0.25" was replaced by "(25/100)".

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                     f/(25/100)-(16)=0 

Step by step solution :

Step  1  :

            1
 Simplify   —
            4

Equation at the end of step  1  :

  1    
  — -  16  = 0 
  4    

Step  2  :

                1
 Divide  f  by  —
                4

Equation at the end of step  2  :

  4f -  16  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   4f - 16  =   4 • (f - 4) 

Equation at the end of step  4  :

  4 • (f - 4)  = 0 

Step  5  :

Equations which are never true :

 5.1      Solve :    4   =  0

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

Solving a Single Variable Equation :

 5.2      Solve  :    f-4 = 0 

 Add  4  to both sides of the equation : 
                      f = 4
