If x = - 6, which inequality is true, - 5 - 3x > 10, - 3 - 5x < - 14 or 2-x < - 3?

If x = - 6

we can subtitution x to every inequality, so:

-5 - 3x > 10

-5 - 3 (-6) > 10

-5 - (-18) > 10

-5 + 18 > 10

13 > 10 [true]

-3 - 5x < - 14

-3 - 5 (-6) < - 14

-3 - (-30) < - 14

-3 + 30 < - 14

27 < - 14 [false]

2 - x < - 3

2 - (-6) < - 3

2 + 6 < - 3

8 < - 3 [false]

So if x=-6, inequality true is - 5 - 3x > 10.
