# How to Get Rid of Absolute Value Bars in Nigeria

To solve an equation containing absolute value, isolate the absolute value on one side of the equation. Then set its contents equal to both the positive and negative value of the number on the other side of the equation and solve both equations.

## When can you drop absolute value bars?

Once we do know a value for “x”, if the expression within the bars is not negative, we can drop the bars; if it is negative, we must change its sign (negating it, making it positive) before dropping the absolute value signs. This same process can be also be used to solve absolute value equations.

### How do you get rid of absolute value bars in inequalities?

If the number on the other side of the inequalitysign is positive, proceed to step 3. Remove the absolute value bars by setting up a compound inequality.
Step 1: Isolate the absolute value |x + 4| – 6 < 9 |x + 4| < 15
Step 4: Solve the compound inequality -19 < x < 11

### How do you manipulate absolute value?

SOLVING EQUATIONS CONTAINING ABSOLUTE VALUE(S)
1. Step 1: Isolate the absolute valueexpression.
2. Step2: Set the quantity inside the absolute value notation equal to + and – the quantity on the other side of the equation.
3. Step 3: Solve for the unknown in both equations.
4. Step 4: Check your answer analytically or graphically.

### When can you drop absolute value?

So, summarizing we can see that if b is zero then we can just drop the absolute value bars and solve the equation. Likewise, if b is negative then there will be no solution to the equation.

### How do you get rid of absolute value on both sides?

Explanation:
1. This is a continuation of my solution given earlier.
2. Solve for x :
3. 5|x+3|−4=8|x+3|−4.
4. Subtract 8|x+3| and add 4 on both sides:
5. Divide both sides by (−3)
6. Subtract 3 from both sides.
7. x=−3 is the ONLY Solution for this example.

### What are the rules of absolute value?

In mathematics, the absolute value or modulus of a real number x, denoted |x|, is the non-negative valueof x without regard to its sign. Namely, |x| = x if x is positive, and |x| = −x if x is negative (in which case −x is positive), and |0| = 0.

### Do all absolute value equations have two solutions?

And represents the distance between a and 0 on a number line. Has two solutions x = a and x = -a because both numbers are at the distance a from 0. An absolute value equation has no solution if the absolute value expression equals a negative number since an absolute value can never be negative.

### Why are there two solutions for absolute value?

1 Answer. Because two numbers have the same absolute value (except 0 ). (The solutions are 73 and −1 .)

### Can there ever be one solution to an absolute value equation?

Summary. Absolute value equations are always solved with the same steps: isolate the absolute value term and then write equations based on the definition of the absolute value. There may end up being two solutions, one solution, or no solutions.

### Which equation has no solution 4x 2 =- 6?

Answer: Option A) |4x2| = – 6 has no solution. Since left hand side of function is in modulus, so it will always gives positive values but right hand side is – 6 , So, there are no values of x that make the equation true.

### What is an example of no solution?

A system of linear equations can have no solution, a unique solution or infinitely many solutions. A system has no solution if the equations are inconsistent, they are contradictory. for example2x+3y=10, 2x+3y=12 has no solution. is the rref form of the matrix for this system.

### How do you tell if an equation has no solution?

The coefficients are the numbers alongside the variables. The constants are the numbers alone with no variables. If the coefficients are the same on both sides then the sides will not equal, therefore no solutions will occur.

### How do you know if a system has no solution?

A system has no solutions if the lines are parallel. When solving the system, if you get a false statement (a number equal to a different number) this means there are no solutions.

### Is 0 0 infinite or no solution?

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

### How do you know if an equation has infinitely many solutions?

If we end up with the same term on both sides of the equal sign, such as 4 = 4 or 4x = 4x, then we have infinite solutions. If we end up with different numbers on either side of the equal sign, as in 4 = 5, then we have no solutions.

### How do you make a system have infinitely many solutions?

An equation can have infinitely many solutionswhen it should satisfy some conditions. The systemof an equation has infinitely many solutionswhen 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.

### What is an example of infinitely many solutions?

When a problem has infinite solutions, you’ll end up with a statement that’s true no matter what. For example: 3=3 This is true because we know 3 equals 3, and there’s no variable in sight. Therefore we can conclude that the problem has infinite solutions. You can solve this as you would any other equation.

### What is symbol for no solution?

Sometimes we use the symbol Ø to represent no solutions. That symbol means “empty set” which means that the set of all answers is empty. In other words, there is no answer.

### What does infinite solution look like?

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.

## How do you deal with absolute value?

To solve an equation containing absolute value, isolate the absolute value on one side of the equation. Then set its contents equal to both the positive and negative value of the number on the other side of the equation and solve both equations. Solve | x | + 2 = 5. Isolate the absolute value.
