We've already learned that we can add or subtract something from both sides of an equation.
So, what if we need to solve something like this?
(Yep, the answer is 5. I know you can see it...
But, we need to learn the game.)
We need to get the x alone...
We need to get this 4 out of here...
What's he doing to the x? Multiplying!
What's the opposite of multiplying? Dividing!
So, divide both sides by 4:
Here's what's going on with this thing:
