# What is the Value of X?

What is the value of X? And what are these letters X, Y, and Z doing in your math equations? In this article, we’ll discuss how to find the value of X in a math problem.

As a bonus, we’ll even explain what is the value of Y and what is the value of Z. Okay, you got us, there’s essentially no difference between X, Y, and Z.

These letters (and others that show up in math problems) are just symbols that we use to show that we haven’t figured out that number yet.

So what are these letters doing in math problems, and what is the value of X? **X, Y, and Z are the most common mathematic (algebraic) variables.**

What are variables? Variables are just numbers that we don’t know yet.

And why do we need to use more than one letter? Well, sometimes we have to figure out two or three numbers that we don’t know yet (known as variables).

Dear Teacher, please stop asking us to find your X. She’s not coming back and we don’t know Y.

## How to Find the Value of X

In math, a variable is a symbol that can stand for different values in a math expression. To find the value of X, you need to solve the math problem. Here’s a simple example:

X = 2 + 5

In this case, X = 2 + 5, so X equals 7.

So what is the value of X in this problem? The value of X is 7.

In a different math problem, the value of X will be different. For example:

X = 8 / 2

In this case, X = 8 / 2.

8 / 2 = 4, so X = 4.

So in this problem, the value of X is 4.

To learn more about variables like X, Y, and Z, Khan Academy is an excellent resource. Here’s a link to their video explaining what a variable is.

Fun fact: the word *variable* comes from the word *vary*. This is because variables can change and represent different numbers in different math problems.

What do algebra teachers have in common with the Backstreet Boys?

They both want you to tell them Y.

## Variables Are Used in Many Different Types of Math Problems

If you’re looking for how to find the value of X in a math problem, you may find it a challenge to find any useful help online.

This is because many different types of math problems use variables. To get guidance on how to find the value of a variable, you’ll need to figure out what specific sort of problem it is.

The Romans had it good. For them, X was always 10.

#### How to Find Explanations for Algebra Problems

Perhaps the easiest way to find the category of your math problem is to look for the lesson where your math textbook introduced this problem.

That lesson will likely have a clear heading that tells you the name of this type of problem. As a bonus, there will also be an explanation of how to solve that type of math problem.

## Using Free Online Resources to Learn Algebra

Another way to get help with algebra is to learn using online resources. The best resource on the web is the free nonprofit Khan Academy.

Khan Academy has extensive math resources including videos, written explanations, and practice problems.

The best thing is, these resources cover math topics from before kindergarten all the way through topics like:

- Trigonometry
- College statistics
- Multivariable calculus
- Differential equations

There’s a reason that Khan Academy has developed a great nationwide education, and they’re best known for math!

There are two main ways to use Khan Academy’s content.

If I had a dollar for every time I solved an algebra problem, I’d have X dollars.

#### Go Through Content in Order

By going through an entire course, such as Khan’s Algebra Basics, or Algebra 1, you can learn things in an order that makes sense.

This is a great way to supplement your school textbook and hear the same ideas presented in a slightly different (and sometimes clearer) way.

#### Learn What You Need

It can still be helpful to use Khan Academy for specific areas where you’re struggling. For example, if you’re having trouble working with and converting units in your algebra equations, you could check out the Khan unit on working with units.
