Multiply -4 and 3: The answer is -12. Then multiply -4 & n. This gives you -4n.
So now we have this: -12 -4n > 32.
Now you add 12 to both sides of the equal sign, because you are doing the inverse operation. So -12 + 12 = 0, so that cancels itself. Then you add 12 to 32, which gives you 44.
(Remember that -12 was canceled out) So now we have -4n > 44. Now we want to get the -4 away from the variable n. This means that we will have to do the inverse operation, therefore, we have to divide -4 on both sides of the equal sign. So -4 divided by -4 = 0, so now we just have n by itself. The last step is to divide the other side by -4. So, 44 divided by -4 equals -11.
That's all you have to doto solve inequalities such as this one! Hope that helped!
SOLUTION: n > -11

- 12 - 4n > - 32
- 4n > - 32 + 12
- 4n > - 20
n <  ------ Inequality sign changes since both sides are being divided by - 4, a value < 0
You can do the check!!
