Answer: -30.

Step-by-step explanation:

We start by multiplying 3 by -5 and 2 by -6.

So the new equation will be -15-12-3.

Then, we can either minus -12 by -3 or we can minus -15 by -12. Either way, we get the right answer.

-15-12=-27

Then, the new equation will be -27-3.

-27-3 = -30.

<u>Answer: </u>-30.
