You can put this solution on YOUR website! Solve the inequality 21/15-3x<0
-----------
If you mean (21/15)-3x<0
Then -3x < -7/5
And x > 7/15
------------------
If you mean 21/(15-3x)<0
Then 1/(15-3x)<0
This fraction will be <0 when 15-3x is negative
Solve 15-3x<0
3x>15
x>5
------------
Comment:
As you can see here, parentheses are important; they change the problem.
