-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
add q:
0 >= -q+q
add 7:
7 >= q
The result is the same.
-q/7 (greater than or equal to sign) -1
How do I do this step by step I am very confused. Please help.

-q/7 ≥ -1
Multiply both sides by 7
-q ≥ -7
q ≥ 7
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. :)
