-2x ≤16 : How to check work when dividing by a negative number in an inequality

Question

-2x ≤16

Would I divide by negative number I understand to flip the inequality sign. In this case, -2x would be greater than or equal to 16. Is there a way to check my work to verify if I can correct?

Thanks!

Hi Tori,

You would divide both sides of the equation by -2 to get your final answer of: x > -8, since 16/-2 = -8. And yes, you do flip the inequality sign since you are dividing by a negative number. :)
