Question

Write down the possible values for n:
-15 < 3n ≤ 6

Answer 1

- 4, - 3, - 2, - 1, 0, 1, 2

Explanation:

Given

- 15 < 3n ≤ 6 ( divide the 3 intervals by 3

- 5 < n ≤ 2

Thus n can have values from - 4 to 2, that is

- 4, - 3, - 2, - 1, 0, 1, 2

Answer 2

Explanation:

Move all terms that do not contain nn from the middle section of the inequality.

−5 <n≤2 - 5 <n≤2
