Pulling out like terms :

 3.1     Pull out like factors :

   24 - 8x  =   -8 • (x - 3) 

Equation at the end of step  3  : -8 • (x - 3) = 0 Step  4  :Equations which are never true :

 4.1      Solve :    -8   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    x-3 = 0 

 
Add  3  to both sides of the equation : 
 
                     x = 3 

One solution was found :                   x = 2
Well it’s obviously C(8) because 8+8=16
