Absolute Value Calculator is a free online tool that displays the absolute value for the given equation. The Mathematics Master online absolute value equations calculator application displays the absolute value of the variable in a matter of seconds speeding up the calculation.

\( |x| = ? \)

The calculator solves the equation by displaying the graph, the solution’s integer values, and their number line representation. Here you can see the graph of equation \( y = |x| \):

Here you can see, whether x = 2 or x = -2, but absolute value of x is 2 in both cases.

Absolute value equations are those that contain variables inside the absolute operator (modulus). In mathematics, an equation with an absolute value expression is known as an absolute value equation.

For instance,\( |x+1|=2\). Here, the absolute expression is \(|x+1|\). The absolute value shows how far away from zero the given integer is. Negative numbers are not permitted in this case. It is the magnitude or size of the number.

For eg., \(|-2| = 2\)

Since \(-2\) is 2 less than the value 0, it. As a result, \(-2\) has an absolute value of 2. These equations are applied to various real-world issues, including estimating distance, figuring out range, variance, etc.

**Example 1: Consider the equation: **\( y = |2x + 3| – 4 \)

To graph this equation, first, we need to find y by assuming values for x. Here we will consider x = -3, -2, -1, 0, 1, 2, 3.

For x = -3, \( y = |2(-3) + 3| – 4 = |-6 + 3| – 4 = |-3| – 4 = 3 – 4 = -1 \)

For x = -2, \( y = |2(-2) + 3| – 4 = |-4 + 3| – 4 = |-1| – 4 = 1 – 4 = -3 \)

For x = -1, \( y = |2(-1) + 3| – 4 = |-2 + 3| – 4 = |-1| – 4 = 1 – 4 = -3 \)

For x = 0, \( y = |2(0) + 3| – 4 = |0 + 3| – 4 = |3| – 4 = 3 – 4 = -1 \)

For x = 1, \( y = |2(1) + 3| – 4 = |2 + 3| – 4 = |5| – 4 = 5 – 4 = 1 \)

For x = 2, \( y = |2(2) + 3| – 4 = |4 + 3| – 4 = |7| – 4 = 7 – 4 = 3 \)

For x = 3, \( y = |2(3) + 3| – 4 = |6 + 3| – 4 = |9| – 4 = 9 – 4 = 5 \)

Now we found these sets of (x, y): (-3, -1), (-2, -3), (-1, -3), (0, -1), (1, 1), (2, 3) and (3, 5). We can use these values to draw a graph. So, the graph for \( y = |2x + 3| – 4 \) will be:

**Example 2: Consider the equation: **\( y = |x| + 2 \)

For x = -3, \( y = |-3| + 2 = 3 + 2 = 5 \)

For x = -2, \( y = |-2| + 2 = 2 + 2 = 4 \)

For x = -1, \( y = |-1| + 2 = 1 + 2 = 3 \)

For x = 0, \( y = |0| + 2 = 0 + 2 = 2 \)

For x = 1, \( y = |1| + 2 = 1 + 2 = 3 \)

For x = 2, \( y = |2| + 2 = 2 + 2 = 4 \)

For x = 3, \( y = |3| + 2 = 3 + 2 = 5 \)

Now we found these sets of (x, y): (-3, 5), (-2, 4), (-1, 3), (0, 2), (1, 3), (2, 4) and (3, 5). We can use these values to draw a graph. So, the graph for \( y = |x| + 2 \) will be:

How do you solve absolute value equations?

- Isolate the absolute value on one side of the equation to solve an equation with an absolute value.
- Then, resolve both equations by setting their respective contents to the positive and negative values of the integer on the other side of the equation.
- Work out \(| x | + 2 = 5\). Isolate the absolute value.

How to solve absolute value inequalities?

Similar processes apply to both calculating an absolute value inequality and an absolute value equation:

- Isolate the absolute value on one side of the inequality.
- Solve the inequality’s “positive version.”
- To solve the inequality’s negative “variant,” multiply the value on the other side by 1, then reverse the inequality sign.

Alternatively, you can use an absolute value inequalities calculator.
