Question

How do you solve the inequality for 5n + -7 < 13 or -5n + 5 < -40

Answer 1

5n + -7 < 13
5n -7 < 13
5n < 13+7
n < 20/5

or

-5n + 5 < -40
-5n +5-5 < -40-5
-5n < -45
n < -45/-5

Answer 2

Which of these would it be?
n < -9 or n > -4 n < -4 or n > -9
n < 9 or n > 4 n < 4 or n > 9

Answer 3

I think I made a mistake in the second one, let me check.

Answer 4

Yeah I did, n < -45/-5 should be this n > -45/-5 , it switches when dividing by a negitive.
so n < 4 or n > 9 , the fourth one. :)
