-2u + 4 > -12
-4 -4
-2u > -16 divide both sides by -2, reversing the symbol

-2u + 4 > -12 solve just like equations
first subtract the 4 over
-2u > -16
then divide by -2 (but when you divide off a neg. coefficient in an inequality statement you have to reverse the symbol)
u <8

1. -2u + 4 > -12
subrtract 4 from both sides
2. -2u > -16
divide -2 from both sides ***remember when you divide by a negative, the greater than, less than sign switches
3. u < 8

-2u + 4 > -12; subtract 4 from both sides
-2u > -12; divide both sides by -2, and because it is a negative we switch the inequality symbol and we get
u < 6

-2u + 4 is greater than -12
So -2u is greater than -12 - 4
So -2u is greater than -16
So 2u is less than16
So u is less than 8.
Sorry, can't find the greater than sign on the keyboard.
