Question 234203: if you have an inequality and you are replacing the variable with a number to see if it is a solution to that given inequality, and the problem looks like this:
4*-2+7>15
do you multiply by negative 2 to both sides? Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! The proper procedure is to multipy the 4*-2.
4*-2+7>15
-8+7>15
-1>15 This says that you don't have the correct solution.
Unless you meant:
4(-2+7)>15
4*5>15
20>15 Now you have a valid proof.
