If you multiply an inequality by a negative number

a. switch the inequality sign
b. keep the inequality sign the same

Step-by-step explanation:

When multiplying, you must switch the inequality sign. This is also true when dividing.

EXAMPLE 1:

-4r < -21

Note: We reversed the inequality sign when we divided by -4

r > 5 1/4

EXAMPLE 2:

x/-5 > 7

Note: We reversed the inequality sign when we multiplied by -5

x < -35

I'm always happy to help :)
