Answer:

6

Step-by-step explanation:

    Pull out like factors :

  -12x + 72  =   -12 • (x - 6)  

Step  2  :

Equations which are never true :  

Solve :    -12   =  0  

A non-zero constant never equals zero.

Solving a Single Variable Equation :  

Solve  :    x-6 = 0  

Add  6  to both sides of the equation :  

                     x = 6
