Here's your shmoop du jour, brought to you by Two-Step Equations.

00:07

Or, for any dogs taking this test...Four-Step Equations.

00:12

Solve the equation -10x + 23 = 353 for x.

00:18

And here are your potential options...

00:21

Okay, so we've got a classic Two-Step equation here.

00:24

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.
