Here's an unshmoopy question you might have seen in your nightmares...

00:08

Which equation is equivalent to 1/3 times 6 minus 3x... minus 2 times 8 plus 4x… equals 3?

00:17

And here are the potential answers...

00:26

So... what is this question asking?

00:29

This one is really just about simplifying a lot of terms.

00:32

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."
