please help me solve this problem 
9 - 8y > 5 + 7y + 2 
I've tried and got the following: 

 9 - 7 > 7y + 8y    CORRECT!

     2 > 15y        CORRECT! 

  2/15 > y          CORRECT! 

That's perfectly correct! (But don't put equal signs
between steps!)

---------------------


 -8y - 7y > 7 - 9   CORRECT

     -15y > -2      CORRECT

        y < -2/15   INCORRECT!!!!!!

That last step is wrong.  You were
correct to reverse the inequality
symbol when you divided through by
-15, but when you divided the
right side, -2, by -15 you should
have gotten +2/15, not -2/15, so 
make that last step

       y < 2/15

and it will be correct.  You do 
realize that this and

    2/15 > y

are equivalent statements, don't you?
