Answer:

n > 1

Explanation:

To solve this inequality, we need to get the variable "n" alone. Follow PEMDAS to do so :

Parenthesis

Exponent

Multiplication

Division

Addition

Subtraction

We can first distribute the -8 to -4 and n to get rid of the parenthesis.

((-8)-4 + (-8)n)

-32 + -8n < -40

Now add 32 to both sides.

-40 + 32 = -8

-8n < -8

Now divide -8 by both sides, don't forget to switch the inequality sign since you're dividing by a negative number.

n > 1
