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
