And yeah, hit pause, try it yourself first.
OK, this question is asking, "can we distribute factors?"
It would be rude not to answer, wouldn't it?

Then just follow the map...
...and we get 2 times x minus 6 minus 3 times y minus 6.
Tricky thing there -- that 3 is NEGATIVE so don't forget to bring along the negative sign.
This expression simplifies to 2x - 3y - 12...
...and the answer is C. Easy peasy. See? No reason for a frowny face.
