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.

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."
