# What value of x will make the equation true

## How do you find values that make an equation true?

To make a true equation,

**check your math to make sure that the values on each side of the equals sign are the same**. Ensure that the numerical values on both sides of the “=” sign are the same to make a true equation. For example, 9 = 9 is a true equation. 5 + 4 = 9 is a true equation.## What value of x will make the equation true 5?

Hence, for

**x = 5**, following equation will be true.## What is the value of x in equations?

The letter “x” is often used in algebra to

**mean a value that is not yet known**. It is called a “variable” or sometimes an “unknown”. In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn’t have to be “x”, it could be “y”, “w” or any letter, name or symbol.## What value of x will make the equation undefined?

A function of x is undefined

**when the denominator is equal to zero**. To find the values that make a function undefined, set the denominator equal to zero and solve the resulting equation.## What values of x make the equation x 2 18x 81 0 true?

The value of x which makes the equation x

^{2}– 18x + 81 = 0 true is**9**.## What value of x makes the equation 2x 5 25 true?

**X = 20**is the solution of the equation 2x + 5 = 25.

## Which is the value of x?

X is an algebraic variable which has

**no defined value**.## What value of x will make the rational expression be equal to 0?

When x = 0, the numerator equals 0 but the denominator does not, therefore it is not an excluded value. Set the denominator equal to 0 and solve for x. The correct answer is

**all real numbers except âˆ’4**.## For what value of x is the rational expression?

In the case of rational expressions, we can input

**any value except for those that make the denominator equal to 0**(since division by 0 is undefined). In other words, the domain of a rational expression includes all real numbers except for those that make its denominator zero.## What is xÂ²?

What is x squared? x squared is

**a notation that is used to represent the expression xÃ—x x Ã— x**. i.e., x squared equals x multiplied by itself. In algebra, x multiplied by x can be written as xÃ—x x Ã— x (or) xâ‹…x x â‹… x (or) xx (or) x(x) x squared symbol is x2 .## How do you find the value of x in a figure?

**Detailed Solution**

- Given: âˆ BAC = 65Â° and âˆ ABC = 72Â°
- Concept used: Sum of all the angles of a triangle is 180Â° Sum of two interior angles is equal to the exterior angle. …
- Calculation: Sum of all the angles of a triangle is 180Â° …
- âˆ´ The value of x is 137Â° Sum of two interior angles is equal to the exterior angle.

## What is the value of x in quadratic equation?

X is

**the variable whose value is unknown**. The value of this unknown variable for which a given equation become true is called root of the equation.## What is xÂ² XÂ² XÂ²?

xÂ²+xÂ² =

**2xÂ²**## How do you solve x2?

## What does 3Â² mean?

**3 squared**is 3Â² = 3 Ã— 3 = 9. 4 squared is 4Â² = 4 Ã— 4 = 16. 5 squared is 5Â² = 5 Ã— 5 = 25.

## What is the answer of XÂ² 9?

One way to solve the quadratic equation x

^{2}= 9 is to subtract 9 from both sides to get one side equal to 0:**x**. The expression on the left can be factored: (x + 3)(x â€“ 3) = 0. Using the zero factor property, you know this means x + 3 = 0 or x â€“ 3 = 0, so x = âˆ’3 or 3.^{2}â€“ 9 = 0## What is x2 Plus x2?

Answer: x squared plus x squared is

**2x**.^{2}## What are the roots of xÂ² 9x 14 0?

Solve x2âˆ’9x+14=0 . The answer is

**x=7 and x=2**.## How many solutions does XÂ² 9 have?

The equation has

**no real solutions**. It has 2 imaginary, or complex solutions.## What are the roots of XÂ² 9?

Answer: The roots of the equation are

**3, and -3**.
