## Algebra Basics: Solving 2-Step Equations - Math Antics  ### Sharing buttons:

Hi, I’m Rob. Welcome to Math Antics.

In the last two Algebra videos, we learned how to solve simple equations

that had only one arithmetic operation in them.

But often, equations have many different operations

which makes solving them a little more complicated.

In this video, we’re going to learn how to solve equations

that have just two math operations in them.

…one addition or subtraction operation, and one multiplication or division operation.

And the concepts you learn in this video will help you solve even more complicated equations in the future.

Now as you might expect, equations that have two arithmetic operations in them

are going to require two different steps to solve them.

In other words, to get the unknown all by itself, you’ll need to ‘undo’ two operations.

But that doesn’t sound too hard, right?

I mean… we learned how to do undo any arithmetic operation in the last two videos.

And that’s true. But there are a couple of reason that make two-step equations a little trickier to solve.

The first is that there are a lot more possible combinations of those two operations.

And the second is that, when there’s more than one operation, you have to decide what order to undo those operations in.

Uh…hello! If you need to know what order to do operations in,

just follow the Order of Operations rules!

You DID watch that video, didn’t you?

I sure did!
