-q/7 (greater than or equal to sign) -1

1. Steve

-q/7 >= -1
-q >= -7
q <= 7

remember to change direction when multiplying/dividing by negative values. It's just a shortcut for the required addition and subtraction:

-q >= -7
0 >= -q+q
7 >= q

The result is the same.

2. Ms. Sue

-q/7 ≥ -1

Multiply both sides by 7

-q ≥ -7

q ≥ 7

I think I somewhat understand this with the way you explained this. This is all new to me.

Thank you for your help. :)
