EDIT: MISTAKE HAS BEEN ADJUSTED.
RESULT NOW CORRECT

This is for #1 only.

x and y integers




and since you expect x and y to be integers, you should try factorization.


You want the INTEGER, so this will be meaning that .

3. 9x3 + x2 + 7 from 5x3 − x − 8 
No. 1 can be answered without algebra, since 14 has only 2 PAIRS of factors. They are: 14 & 1, and 7 and 2. 

Now use the 2nd clue to determine which pair pertains to this problem.

By the way, last time I checked, 2 times - 7 DID NOT EQUAL 14, and I don't believe this has changed.
