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 :

                     3^2*x-(15)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (32 • x) -  15  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   9x - 15  =   3 • (3x - 5) 

Equation at the end of step  3  :

  3 • (3x - 5)  = 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  :    3x-5 = 0 

 Add  5  to both sides of the equation : 
                      3x = 5
Divide both sides of the equation by 3:
                     x = 5/3 = 1.667
