Question 57736
If you ever get an answer from this site, look the tutor up to see if they're qualified.  There's a few jerks out there who enjoy messing with sites like this.  Also, remember that people are solving your questions.  Even the best of us can make an occasional mistake in typing, interpretting your question, or even in calculation.  I made a mistake last week myself.  Always double check us, we're not perfect.

4R - 7 < 7R - ( R + 7 )

4R-6R-7<6R-6R-7
-2R-7<-7
-2R-7+7<-7+7
-2R<0
-2R/-2>0/-2  Whenever you multiply or divide by a negative number you must flip the inequality symbol.
