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 :

                     7*f+8-(5*(f-2))=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (7f + 8) -  5 • (f - 2)  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   2f + 18  =   2 • (f + 9) 

Equation at the end of step  3  :

  2 • (f + 9)  = 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  :    f+9 = 0 

 Subtract  9  from both sides of the equation : 
                      f = -9
