Answer:

x = 3

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Step by step solution :

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  -9 + 3x  =   3 • (x - 3)  

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    x-3 = 0  

Add  3  to both sides of the equation :  

                     x = 3
