Not sure if this is a question, Jeron. :) So, let me review with you rules for inequalities:
You can add the same value to or subtract the same value from both sides of an inequality, and the inequality is still true.
You can multiply or divide both sides of an inequality by the same POSITIVE number, and the inequality is still true.
If you multiply or divide both sides of an inequality by the same NEGATIVE number, you must flip the inequality sign around. For example, if a>b, and you multiply through by -2, then -2a<-2b.
Does this help? :)
