Answer:
any number greater than -2 
Step-by-step explanation:
4 - 5y < 14
step 1: subtract 4 from each side "
4 - 4 cancels out
14 - 4 = 10
now we have -5y < 10
step 2: divide each side by -5
-5y/-5=y
10/-5=-2
( IMPORTANT NOTE: WE MUST FLIP THE INEQUALITY SIGN IF WE DIVIDE BY A NEGATIVE NUMBER) 
We would be left with y > -2
