Given the function f (x) = 2 (x+6) - 4, for what values of x isf (x) = 6?

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
