Answer:

n =7 or n = -17/3

Step-by-step explanation:

10 - |3n - 2| = -9  (subtract 10 from both sides)

- |3n - 2| = -9 - 10

- |3n - 2| = -19   (multiply both sides by -1)

|3n - 2| = 19

(3n - 2) = 19 or (3n - 2) = -19

For (3n - 2) = 19,

3n - 2 = 19

3n = 21

n =7 (answer)

For (3n - 2) = -19,

3n - 2 = -19

3n = -17

n = -17/3 (answer)
