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 :

                (3*(8*x+24))/12-(9-3*(x-4))=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (3•(8x+24))
  ———————————-(9-3•(x-4))  = 0 
      12     

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   8x + 24  =   8 • (x + 3) 

Equation at the end of step  3  :

  24 • (x + 3)    
  ———————————— -  (21 - 3x)  = 0 
       12         

Step  4  :

            24 • (x + 3)
 Simplify   ————————————
                 12     

Equation at the end of step  4  :

  2 • (x + 3) -  (21 - 3x)  = 0 

Step  5  :

Step  6  :

Pulling out like terms :

 6.1     Pull out like factors :

   5x - 15  =   5 • (x - 3) 

Equation at the end of step  6  :

  5 • (x - 3)  = 0 

Step  7  :

Equations which are never true :

 7.1      Solve :    5   =  0

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

Solving a Single Variable Equation :

 7.2      Solve  :    x-3 = 0 

 Add  3  to both sides of the equation : 
                      x = 3
