Question 313038: 9(y-3) < 9y-6
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! 9(y-3)<9y-6
9y-27<9y-6
Subtract 9y from each side:
-27<-6
Since all the variables subtracted out, this statement has no variables. It is either TRUE (always true!) or FALSE (always false!). In this case, the statement is TRUE, so the inequality is called an IDENTITY. The solution is ALL REAL VALUES of y.
