Answer:
C: {−5, 1)
Step-by-step explanation:
Starting with −2|−2x−4|=−12, divide both sides by -2:
|−2x−4| = 6
Reduce this by dividing all terms by 2:
|-x - 2| = 3
This is equivalent to x + 2 = 3 and x + 2 = - 3
Solving thse two equations, we get x = 1 and x = -5
And so the solution set is C: {−5, 1)
