There is no cone to surface
-6x -17 ≥ 8x + 25
Subtract 8x from each side:
-14x -17 ≥ 25
Add 17 to each side:
-14x ≥ 42
Divide each side by 14 :
-x ≥ 3
Change the signs. (Multiply each side by -1.)
That's when you have to flip the inequality symbol.
x ≤ -3
It's commutative property because of the order
