Easiest Methods of How to Solve X Like A Professional

how to solve x

How to solve x: I was one of those students who could never understand algebra. Starting to solve such an equation was like getting into cold water in winters. I always ended up not knowing how to solve for X. If you are also one of them, this blog is for you.

Well, several students are scared with the name of mathematics. Especially when they get to know that they have to solve the algebraic equation and find the value of X variables. 

Thus, in this blog, you will learn how to solve for X with simple steps and tricks. It will help you understand the reasoning of equations and what steps and methods you need to follow to find the value of X. 

What is an x equation in maths? 

An equation means when the two sides have conjunction = and both left-hand and right-hand sides are equal. For example – 

10 -X = 5 

Here the value of x is 5.

Thus, 10 – 5 = 5. Hence both sides are equal. 

Here X is a variable. It can change as per the equation. 

When we find a value for x, then it is called a solution. Like the solution in this equation is 5. 

Let’s learn how to solve X 

In mathematics, every student encounters algebra in school. Algebra is one of the types of maths having variables representing certain numerical values. X is one of such variables which is used in algebra. And likewise, there are other variables also like Y, Z, A, etc. Now you are stuck with how to solve X or how to find the value of X.

In order to learn to solve the value of X, you first need to learn the basics of algebraic operations. 

Isolate the x on one side

One of the methods of solving X is to isolate the x on one side, and then you have to shift the other numbers in the equation to the other side. If the numbers are positive on one side, it will become negative when you shift to the other side. 

For example, Your equation is

X + 9 = 16. So in this equation, if you send the +9 from the left side to the right side, it will become -9. Then it will be as follows – 

X = 16- 9.

Now the X variable is isolated in the equation. So it has become easy for you to bring out the value of X by solving the right-hand side. Now you have to subtract 9 from 16 in order to get the value of X.

So the answer is as follows – 

X = 16 – 9 = 5.

This is the value of X is 5.

Suppose your equation is X – 5 = 4.

The second method for how to solve x through isolation is to send the negative number to the other side, and then it will become positive on the other side. 

Now you are required to send the negative number that is -5 from the left side to the right side. As you can see below, when you shift a negative number to the other side, it will become a positive number. Thus, your equation will be as follows 

X = 4 + 5. 

Suppose your equation has a multiplication. 

For example – X x 5 = 25.

Now you must be thinking about how to solve X. Then don’t stress out it is also simple like others. Now you have to gain the isolation method. So for isolating X you need to send the 5 from the left side to the right side. 

Since there is a multiplication sign, when you send a multiplication symbol to the other side, it will be in the division. Thus your equation will be as follows. 

X = 25 /5 = 5.

So the value of X is 5.

Now suppose you have a division number equation. 

For example X / 5 = 5.

Yes, you are right; it will be solved like the multiplication equation. So if you are stuck on how to solve x in such an equation, don’t worry; just follow these guides. 

So firstly, you have to isolate the X, and for isolating X you need to send the 5 from the left side to the right side. And the trick is what you do with the division sign. So when you shift the Division from one side to the other side, then it becomes multiplication. Thus your equation will become as follows – 

X = 5 x 5 = 25.

So the value of X is 25. 

Suppose if you have more than one number in the equation.

For example, X -1 + 6 = 10. Now you must be thinking how to solve X in such equations.  

Now also it is very easy you just have to follow the above rules. So you need to isolate the X, and for that, you have to send -1 and +6 from the left side to the right side. When you take -1 to the right side, it will become +1, and when you take +6 from the left side to the right side, it will become -6. So the equation will read as follows –

X = 10 +1 -6 = 5.  

Methods: How Do You Solve For X for Beginners

Following are the methods used to solve the value of X.

1. Using Basic Linear Equations

A Basic Linear Equation is an algebraic equation in which each term has an exponent of one, and the graphing of the equation occurs in a straight line. Look at the following example to solve X with Basic Linear Equation.

Check Your Work

2^2 (4+3)+9-5 = 32

4 (4+3)+4 = 32

16+12+4 = 32


2. With Exponent

It is a symbol written above and to the right of a mathematical expression to show the method of raising to a power. Let’s take an example:

To Check you work, put 4 and -4 in the place X. For example,

2X^2 +12 = 44

2(4)^2 +12 = 44

2 X 16 + 12 = 44

32 + 12 = 44


3. Using Fraction

A fraction is a number that can be expressed as a proportion of two whole numbers. For example, ½ and ¾ are both fractions. Let’s learn from the example below:

Check Your Work

X+3/6 =2/3

1+3/6 = 2/3 (cross multiply)

3 (1+3) = 2(6)   

3+9 = 12


4. Applying Radical Sign

Radical Sign is the figure for square root. It is the number that, when multiplied by itself, gives the original number. Following is the example.

Check Your Work

√( 2x+9) – 5 = 0

√( 2(8) + 9) – 5 + 5 = 0 + 5

√ (2(8)+9) = 5

Now, square both sides to remove square root.

2(8)+9 ^2 = 5^2

16 + 9 – 9 = 25 – 9

16 = 16

5. Using Absolute Value

The symbol “|” is located on both sides to mean “Absolute Value,” so we write: |−8| = 8. Let’s take an example to solve X using Absolute value.

Check Your Work by putting both the values of X. For example; we put the x=3;

|4X + 2| – 6 = 8

|4(3) + 2| – 6 + 6 = 8 + 6

|4(3) + 2| = 14

Remove the absolute value and solve the equation,

4 X 3 + 2 – 2 = 14 – 2

4 X 3 = 12

12 = 12


We consider algebraic equations and mathematics tough, but it is easy if you know the reasoning and logic. So you just need to understand the concepts then maths will become easy for you.

What number is X in Algebra?

The letter “x” is always used in algebra; that value is unknown. It is called a “variable” or an “unknown.” In x + 2 = 7, x is a variable, but we can work out its value if we try!

What is the initial step to solving for x?

The first step to solving x is getting x only on one side of the equation. Remember the algebraic golden rule: What you do to one side of the equation, you must do to the other side. That’s how the equation stays equal.
