Move the X's on the left of the inequality and the nubers on the right.

When you change sides, you change sign.

e.g.

21-3x>3 = -3x>3-21 (notice i changed 21 to -21) = 13x>-18 = DIVIDE -18 BY 13 = x>-1.38

In questions like these you change the number to a posotive number:

-x<-3 = x< 3 (imagine there is a one infront of the x, it would then loook like this ; -1x<-3. Then divide -3 by -1 and that will give you 3 because a minus multiplied by a minus is a plus...)

Hope this helps...
