Hopefully we don't have... two left hands.
- 00:28
To solve, we need to get x all by itself.
- 00:31
And when we say "by itself," we mean no numbers, no negative symbols... no nothing.
- 00:36
With that in mind, we first subtract 23 from both sides:
- 00:39
And we get -10x = 330.
- 00:41
Next, divide 330 by -10 to leave x alone.
- 00:45
x = -33.
- 00:46
And... that's it. Our answer is B.
