The problem |x|-5=3 is an absolute value equation. to find what x equals you have to get x by itself by adding 5 to each side.
|x|-5=3
+5 +5
|x|=8
|x| is equal to 8, but is also equal to -8 because the absolute value bars mean that anything inside them is turned positive. Check your answer by substituting 8 and -8 in for x.
|8|-5=3?
|-8|-5=3?

How can you use a number line to solve an absolute value equation?
An absolute value may not need a number line to solve. Absolute value means the distance form zero regardless of the sign.
In math what is an absolute equation?
Firstly, we have to look at what the word absolute implies first. Absolute value can be represented as either lxl or abs(x). The word absolute means that for any number or equation it is positive. e.g. l-7l = 7. OR l3l = 3. Back to your question, since u just ask what is an absolute equation, i would not go through how to solve and graph them because its just too complicated at this stage. Absolute equation can be in the form of; lx-3l = 4 l4-xl > l5+xl <=== This is an inequality. lx+3l = l1+2xl
How many solutions do absolute value equations have?
An equation with absolute values instead of simple variables has twice as many solutions as an otherwise identical equation with simple variables, because every absolute value has both a negative and a positive counterpart.
What is the corner point of the graph of an absolute value equation called?
vertex
How do you format an absolute value in Excel?
In excel cell, type =ABS(XXXX). It will return the absolute value of the number or equation you put within the parentheses.
How do you solve absolute-value equations and inequalites?
Absolute Value means the distance from 0, and so you should solve the equation with the number inside the Absolute Value lines as a positive and then solve again as a negative.
How can you use a number line to solve an absolute value equation?
An absolute value may not need a number line to solve. Absolute value means the distance form zero regardless of the sign.
What are the characteristics of an absolute value equation?
Mainly that somewhere in the equation there is an absolute value, usually of an expression that involves the variable.
How do you solve absolute value inequalities?
The absolute value of something is also the square root of the square of that something. This can be used to solve equations involving absolute values.
What is an absolute personal equation?
An absolute personal equation is the difference between an observed value and a standard value assumed as being true.
What does absolute value inequality mean?
It is an equation used to anwer an absolute value inequality.
What are the solutions of the equation open absolute value x close absolute value minus 19 equals negative 3?
You can write this as two equations, and solve them separately. The two equations are:x - 19 = -3and:-x - 19 = -3
What do you call a V-shape on a graph?
That is a result of an absolute value equation. So an Absolute Value Graph
Absolute value inequalities?
What's your question? To solve an absolute value inequality, knowledge of absolute values and solving inequalities are necessary. Absolute value inequalities can have one or two variables.
How do you solve integers and absolute value?
To solve equations with absolute values in them, square the absolute value and then take the square root. This works because the square of a negative number is positive, and the square root of that square is the abosolute value of the original number.
How do you solve absolute value involving fractions?
Fractions make no difference to absolute values.
What is the corner point of a graph of an absolute value equation?
It is sometimes the point where the value inside the absolute function is zero.
