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*(x-3)-(3)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  3 • (x - 3) -  3  = 0 

Step  2  :

Pulling out like terms :

 2.1      Pull out     3 

After pulling out, we are left with :
      3 • ( 1  *  (x-3) +( (-1) ))

Equation at the end of step  2  :

  3 • (x - 4)  = 0 

Step  3  :

Equations which are never true :

 3.1      Solve :    3   =  0

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

Solving a Single Variable Equation :

 3.2      Solve  :    x-4 = 0 

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