Add 5 to both sides. Then 45/v is greater than or equal to -8.
Mult. both sides by v to obtain "45 is greater than or equal to -8v."
Solving for v: v is smaller than or equal to -45/8, or smaller than or equal to -5 5/8. Does -3 satisfy this criterion? NO. Eliminate -3.
Does -9 satisfy this criterion? YES. And so on.
