-8x > -64
Divide both sides by -8. Turn the sign around because you're dividing by a negative number.
x < 8
-8x > -64
A little confused on how this is done.

one way is to remember to change direction when multiplying/dividing by negative values. So,
-8x > -64
x < 8
This is just a shortcut to doing the addition/subtraction to swap sides:
-8x > -64
add 8x:
0 > 8x-64
add 64:
64 > 8x
8 > x
no change of direction needed here, but the 8x still winds up on the proper side of the arrow
