It is similar to an equation

-3x-6<-5x-2

-3x+5x<-2+6

2x<4

x<4/2

x<2

* when solving inequality problems you need to switch signs when you divide a side by a negative number.

Ex.

-3x-6<-5x-2

-6+2<-5x+3x

-4<-2x

When you divide -4 by -2, switch the lesser sign to greater sign.

-4/-2>x

2>x

Which gives you the same result either way.

x<2
