Is the question:
5y - 2 ≥ 14 - 3y ?
if so
5y - 2 ≥ 14 - 3y
8y ≥ 16
y ≥ 2

Careless presentation even although y does lie next to u on the keyboard !

5y - 2 ≥ 14 - 3u
8y ≥ 16
y ≥ 2

Over to u !

5y - 2 >> 14 - 3u
5y - 2 - 14 >> 14 - 3u - 14
5y - 16 >> 3u
(5/3)y - 16/3 >> u

U must be less than or equal to (5/3)y - (16/3)


Hope that's the answer you were looking for.
