Write a multipulcation equation and a division equation which has a solution of -5

We can start from and multiply/divide both sides to generate an equation that has -5 as a solution. For example, if we multiply both sides by 3, we have

And this equation must be solved by dividing both sides by 3.

Vice versa, if we divide both sides by 2, we have

And this equation must be solved by multiplying both sides by 2.
