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*(x-3)-(5*(x+3))=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (7 • (x - 3)) -  5 • (x + 3)  = 0 

Step  2  :

Equation at the end of step  2  :

  7 • (x - 3) -  5 • (x + 3)  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   2x - 36  =   2 • (x - 18) 

Equation at the end of step  4  :

  2 • (x - 18)  = 0 

Step  5  :

Equations which are never true :

 5.1      Solve :    2   =  0

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

Solving a Single Variable Equation :

 5.2      Solve  :    x-18 = 0 

 Add  18  to both sides of the equation : 
                      x = 18
