## How Does Solve For x Calculator Work?

An algebraic expression can be defined as a mathematical expression that consists of coefficients, variables, and constants. The terms of such an expression are linked together by addition, subtraction, multiplication, and exponentiation. When two algebraic expressions are combined with the help of an "equal to" sign, an equation is formed. Given below are the steps to solve such an equation.

- Bring the variable (x in this case) to the L.H.S of the equation.
- Bring the constant terms to the R.H.S of the equation.
- By performing the required arithmetic operations solve the R.H.S.
- If x has any coefficients then divide both the L.H.S and R.H.S with this number.
- Further, if the degree of x is 1 then we have found the value of x.
- Suppose the degree of x is n (where n is any number greater than 1). Then we have to take the n
^{th}root of the equation to obtain the value of x.

## Solved examples on Solve For x Calculator

**Example 1:**

Solve the value of x for given x^{2} - 25 = 0 and verify it using the solve for x calculator.

**Solution:**

x^{2} - 25 = 0

x^{2} = 25

x = +5, -5

Therefore, the value of x is -5 and 5.

**Example 2:**

Solve the value of x for given 3x + 6 = 0 and verify it using the solve for x calculator.

**Solution:**

3x = -6

x = -6/3

x = -2

Similarly, you can use the solve for x calculator to find the value of x for the following:

- 5x
^{3}+ 2x + 5 - 4x
^{2}+ 5x - 7
