Answer 4

Okay, first we multiply -5 to both sides.

What's -5 * 15?

Answer 5

That is -75

Answer 6

And if only if you want to transpose a negative you need to change the equality sign

Answer 7

Yes, and we switch the sign because we multiplied by a negative number, that gives us:

\(t \le -75\)
