woohoo921 you have to think through the arithmetic operations that you're performing here:
You're essentially dividing the inequality bybd .
Can you do that?
Well, you can absolutely do that, as long as you're confident thatbd >0
Ifbd = 0 you can't divide bybd . Ifbd < 0 you have to flip the direction of the inequalitysign.
