≤ ≥
The alligator works the same way, except it may also eat something equal to that on the other side of the sign.  It is fussy, but not that fussy.
I assume this is...
Let's multiply both sides by -9
Because we are multiplying by a negative number on both sides, the sign must switch--in response to negativity, the alligator is changing direction.
And because a negative number multiplied by another negative number renders a positive result...
And because a positive number multiplied by a negative number renders a negative result...
Another number greater than or equal to -63 resolves this and satisfies the alligator.
Unless I misunderstood you and the equation is...
Let's multiply both sides by t...
Let's multiply both sides by 1/7...
