Question 308704: 7(10x - 15) > 5(14x - 10)
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! 7(10x-15)>5(14x-10)
70x-105>70x-50
Subtrac 70x from each side:
-105 > -50
Since all the variable subtracted out, there is nothing left but numbers. The inequality is either TRUE (always true!), or it is FALSE (always false!).
In this case, the inequality -105>-50 is FALSE, so there is NO SOLUTION. This is called a CONTRDICTION.
