Answer:
The answer to your question is x = -1
Step-by-step explanation:
Data
f(x) = 2(x + 6) - 4
f(x) = 6
Process
1.- Equal the function to 6
6 = 2(x + 6) - 4
2.- Expand
6 = 2x + 12 - 4
3.- Simplify like terms
6 = 2x + 8
4.- Substract 8 in both sides
6 - 8 = 2x + 8 - 8
5.- Simplify
- 2 = 2x
6.- Divide both sides by 2
-2/2 = 2x/2
7.- Simplify
-1 = x
