You can put this solution on YOUR website!
-3w%2B3%3E=18

Subtract 3 from each side:
-3w%3E=15

Here is the tricky step! When you muliply or divide both sides of an inequality by a negative number, you must REVERSE the inequality sign!
%28-3w%29%2F%28-3%29+%3E=+15%2F%28-3%29+
w%3C=-5

For a simpler explanataion of this than the one you have in traditional textbooks, please see my website by clicking on my tutor name "rapaljer" anywhere in algebra.com. Look for about the second link on my home page, which is "Basic, Intermediate, and College Algebra: One Step at a Time." Click on "Basic Algebra", "Chapter 1", and look for "Section 1.11 Inequalities." My own students and students who discover my website tell me that I have a "user-friendly" explanation. I hope you will find it helpful.
