# Examples of no solution equations

## What type of equation has no solution?

A system of

**linear equations**has no solution when the graphs are parallel.## Which equation has no solution 4x 2 =- 6?

It returns only a positive value. ⇒ |4x – 2| = -6 has a negative value -6. |3x – 6| = -5 etc will not have solutions for x. Thus, the equation

**|4x – 2| = -6**has no solution.## What is an example of no solution on a graph?

System of Linear Equations with No Solutions

The red line is the graph of y=4x+2, and the blue line is the graph of y=4x+5. **When two equations have the same slope but different y-axis, they are parallel**. Since there are no intersection points, the system has no solutions. Now let’s try an example.

## What is no solution in math?

Sometimes equations have no solution. This means that

**no matter what value is plugged in for the variable, you will ALWAYS get a contradiction**.## How do you tell if a problem has no solution?

When a problem has no solution

**you’ll end up with a statement that’s false**. For example: 0=1 This is false because we know zero can’t equal one. Therefore we can conclude that the problem has no solution.## What makes a line no solution?

No Solution: When the lines that make up a system are parallel, there are no solutions because

**the two lines share no points in common**.## Is 0 0 infinite or no solution?

infinite solutions

Since 0 = 0 for any value of x, the system of equations has

**infinite solutions**.## What is a line or no solution?

There are a few ways to tell when a linear system in two variables has no solution: Solve the system – if you solve the system and get a nonsense equation (such as 0 = 1), then there is no solution. Look at the graph –

**if the two lines are parallel (they never touch), then there is no solution to the system**.## What is a contradiction equation?

**An equation that has no solution**, such as x = x +1, is called a contradiction. 1.

## What’s a conditional equation?

A conditional equation is

**an equation that is true for some value or values of the variable, but not true for other values of the variable**. In Hannah’s case, we have that the equation is true for 10 but is not true for other values of x, such as 1. Therefore, the equation is a conditional equation.## What is an infinite solution equation?

An infinite solution

**has both sides equal**. For example, 6x + 2y – 8 = 12x +4y – 16. If you simplify the equation using an infinite solutions formula or method, you’ll get both sides equal, hence, it is an infinite solution. Infinite represents limitless or unboundedness. It is usually represented by the symbol ” ∞ “.## How do you know if a quadratic equation has no solution?

A quadratic equation has no solution

**when the discriminant is negative**. From an algebra standpoint, this means b^{2}< 4ac. Visually, this means the graph of the quadratic (a parabola) will never touch the x axis.## How do you know if an equation is conditional or identity?

Identifying Types of Linear Equations

If solving a linear equation leads to: a true statement such as 0 = 0, then equation is an identity and the set of real numbers is its solution set. a single solution, then equation is conditional and its solution consist of a single element.

## How many solutions does an equation have?

An equation can have

**infinitely many solutions**when it should satisfy some conditions. The system of an equation has infinitely many solutions when the lines are coincident, and they have the same y-intercept. If the two lines have the same y-intercept and the slope, they are actually in the same exact line.## How many algebraic identities are there in class 9?

The

**three**algebraic identities in Maths are: Identity 1: (a+b)^{2}= a^{2}+ b^{2}+ 2ab. Identity 2: (a-b)^{2}= a^{2}+ b^{2}– 2ab.## What is an example of an identity equation?

An identity is an equation which is always true, no matter what values are substituted.

**2 x + 3 x = 5 x**is an identity because 2 x + 3 x will always equal regardless of the value of . Identities can be written with the sign ≡, so the example could be written as 2 x + 3 x ≡ 5 x .## What is an equation with only one solution?

The linear equations in one variable is an equation which is expressed in the form of

**ax+b = 0**, where a and b are two integers, and x is a variable and has only one solution. For example, 2x+3=8 is a linear equation having a single variable in it. Therefore, this equation has only one solution, which is x = 5/2.
