What is -2-8?

sammixboo (sammixboo):

First subtract 8 on both sides of the equation -2x + 8 - 8 < -2 - 8 -2x = <-2 - 8

OpenStudy (anonymous):

-10

sammixboo (sammixboo):

So yes, what is -2 - 8?

TheSmartOne (thesmartone):

So -2x<-10 What is -10/-2??

OpenStudy (anonymous):

5

TheSmartOne (thesmartone):

And remmber the sign will have to flip

TheSmartOne (thesmartone):

So we finally get x>5 :D

OpenStudy (anonymous):

so its x>5?

sammixboo (sammixboo):

Correct, so whe have -2x = -10 Now divide -2 on both sides of the equation -2x/2 < -10/-2 x > -10/-2 (flip the < sign to > because we are dividing a negative)
