So, let's say you have an equation like this:

2x + 3 = 9

And you want to figure out what number x is equal to.

Well, to solve for x, you need to isolate it on one side of the equation.

Here's what you do:

1. Start by getting rid of any numbers that are on the same side of the equation as x.

In our example equation, we have 3 on the same side as x, so let's get rid of it.

To do this, we can subtract 3 from both sides of the equation:

2x + 3 - 3 = 9 - 3

Now the 3s cancel out on the left side, and we have:

2x = 6

2. Next, we want to get x all by itself on one side of the equation.

To do this, we need to divide both sides by the number that's in front of x.

In our equation, the number in front of x is 2.

So, we can divide both sides by 2:

2x ÷ 2 = 6 ÷ 2

On the left side, the 2s cancel out, and we have:

x = 3

And that's it! We've solved for x.

So in our original equation, 2x + 3 = 9, x is equal to 3.

I hope that makes sense! Let me know if you have any questions.
