So... let's.

00:33

We are really just distributing multipliers, which look like this, being careful with the negatives...

00:39

...and we get 6 over 3, which is 2.

00:41

Then we get negative 3x over 3, or just negative x when you cancel out the threes.

00:47

That gives us 2 minus x minus 16...

00:51

minus 8x...

00:54

which equals 3.

00:57

We've got -14 on the left now... and negative 9x...

01:02

...so we have negative 9x minus 14 equals 3.

01:06

And there we go. Our answer is C.

01:09

As in, "Careful."
