For this case we must solve the following inequality:
[tex]- \frac {t} {5}> 15[/tex]
We follow the steps below:
We multiply by 5 on both sides of the inequality:
[tex]-t> 15 * 5\\-t> 75[/tex]
We multiply by -1 on both sides of the inequality. We must bear in mind, that when multiplying by -1, the sense of the inequality changes.
[tex]t <-75[/tex]
