To solve the equation \( 6 - 2|3x + 2| - 9 = -11 \), we first simplify the left-hand side:
1. Combine constants on the left:
\[
6 - 9 = -3
\]
This simplifies our equation to:
\[
-3 - 2|3x + 2| = -11
\]
2. Now, isolate the absolute value term:
\[
-2|3x + 2| = -11 + 3
\]
\[
-2|3x + 2| = -8
\]
3. Divide both sides by -2:
\[
|3x + 2| = 4
\]
Now we have two cases to solve for \( |3x + 2| = 4 \):
### Case 1:
\[
3x + 2 = 4
\]
Subtract 2 from both sides:
\[
3x = 2
\]
Now, divide by 3:
\[
x = \frac{2}{3}
\]
### Case 2:
\[
3x + 2 = -4
\]
Subtract 2 from both sides:
\[
3x = -6
\]
Now, divide by 3:
\[
x = -2
\]
### Final Solutions:
The solutions to the equation \( 6 - 2|3x + 2| - 9 = -11 \) are:
\[
x = \frac{2}{3} \quad \text{and} \quad x = -2
\]
Thus, the correct response is:
\[
x = -2 \quad \text{and} \quad x = \frac{2}{3}
\]
