Answer:
-2
Explanation:
Simplifying 
6(2x + 4) = 0 
 
Reorder the terms: 
6(4 + 2x) = 0 
(4 * 6 + 2x * 6) = 0 
(24 + 12x) = 0 
 
Solving 
24 + 12x = 0 
 
Solving for variable 'x'. 
 
Move all terms containing x to the left, all other terms to the right. 
 
Add '-24' to each side of the equation. 
24 + -24 + 12x = 0 + -24 
 
Combine like terms: 24 + -24 = 0 
0 + 12x = 0 + -24 
12x = 0 + -24 
 
Combine like terms: 0 + -24 = -24 
12x = -24 
 
Divide each side by '12'. 
x = -2 
 
Simplifying 
x = -2
