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 :

                     -11*f-(7*(1-2*f)+5)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  -11f -  (7 • (1 - 2f) +  5)  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   3f - 12  =   3 • (f - 4) 

Equation at the end of step  3  :

  3 • (f - 4)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    3   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    f-4 = 0 

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