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?

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.
