I'm missing one little thing in this question. i do not understand why it is a inequality with a union. i understand the concept of the union but im missing something. Thanks all.
(1/2-x) < 3
...sorry if its too easy im just stuck. thanks
Which of these is the correct representation of your question?
1) $\displaystyle \frac{1}{2}-x<3$
2) $\displaystyle \frac{1}{2-x}<3$
Sounds like it might be 2) so you're dealing with rational inequalities. Try here these two sites for some insight:
