Answer:
     x = 14
Step-by-step explanation:
 1.1     Pull out like factors :
   2x - 20  =   2 • (x - 10)  
Equation at the end of step  1  :
Step  2  :
Equations which are never true :
 2.1      Solve :    2   =  0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
 2.2      Solve  :    x-10 = 0  
 Add  10  to both sides of the equation :  
                      x = 10  
One solution was found :
                   x = 10
