Hi,

I understand why the answer is B. My confusion comes from setting them equal to each other, so the “a” drops out.

bc = (b+c)

From here the answer would then be A. I thought you could do this for QC problems.

We don’t divide by variables , just add or subtract them

To add to that you CAN divide by a variable if it is positive (cannot be 0 either)

Dividing something by a negative integer changes the direction of inequality

or example

If A = 15, B = 20

B > A

But if I divide them by -5, I get

A = -3, B = -4

In which case A < B
