Solution - Linear equations with one unknown

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   12x - 20  =   4 • (3x - 5) 

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

 2.1      Solve :    4   =  0

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

Solving a Single Variable Equation :

 2.2      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
