What are the 3 steps to solving absolute value equations?
We will be using the following 3-step process that can be used to solve any absolute value equation:
- STEP ONE: Isolate the Absolute Value.
- STEP TWO: Solve for Positive AND Solve for Negative.
- STEP THREE: Check Your Answer.
How do you find the absolute value of an algebraic expression?
Since we’re multiplying that will turn into positive eight and then we have the absolute value of negative six plus eight well negative six plus eight gives us positive two.

What does absolute value mean in algebra?
Absolute value describes the distance from zero that a number is on the number line, without considering direction. The absolute value of a number is never negative. Take a look at some examples. The absolute value of 5 is 5. The distance from 5 to 0 is 5 units.
How do you simplify absolute value expressions with variables?
What are the rules of absolute value?
The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign. For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5.
How do you solve absolute value equations with variables on both sides?

What’s the absolute value of 9?
9
The absolute value of 9 is 9. (9 is 9 places from 0.)
Do you multiply absolute value?
You can’t multiply across the absolute value bars, so you must first find the absolute value of the number inside them. Since the absolute value of is , the operation becomes . When absolute value bars enclose an expression that includes operations, the expression must be evaluated before finding the absolute value.

What’s the absolute value of 2?
For example,|2| represents the absolute value of 2. To calculate it, it is important to have some familiarity with the representation of integers on a number line.
What’s the absolute value of 4?
Therefore, the absolute value of -4 is 4.
How do you multiply a number with an absolute value?
What is the first step in solving an absolute value equation?
| Step 1: Isolate the absolute value | |3x – 6| – 9 = -3 |3x – 6| = 6 |
|---|---|
| Step 2: Is the number on the other side of the equation negative? | No, it’s a positive number, 6, so continue on to step 3 |
| Step 3: Write two equations without absolute value bars | 3x – 6 = 6 |
| Step 4: Solve both equations | 3x – 6 = 6 3x = 12 x = 4 |
How do you solve an absolute value equation with one solution?
How To Solve an Absolute Value Equation when There is Only One …
What is the absolute value of 15?
We can see the distance between this number and the zero is $15$ unit, and according to the absolute value definition we know that it is the distance from zero and the integer. Therefore, the absolute value of $ – 15$ is $15$, which can also be represented as $\left| { – 15} \right| = 15$.
What’s the absolute value of 11?
The absolute value of any positive number is the number itself, so 11 has 11 as an absolute value. Also, the absolute value of a negative number is its (positive) opposite, so also has 11 as an absolute value.
What do you do with numbers outside the absolute value?
Solve an absolute value equation that contains a number outside the absolute value bars by algebraically moving that number to the side of the equation opposite the variable.
Why do absolute value equations have two answers?
1 Answer. Because two numbers have the same absolute value (except 0 ).
What is the absolute value of 42?
The absolute value is the distance between a number and zero. The distance between −42 and 0 is 42 .
What is the absolute value of 7 *?
7
|7| = 7 means the absolute value of 7 is 7.
