The solution to the absolute value equation 2|x + 8| - 4 = 16 is x = 2 or x = -18
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Given the equation:
2|x + 8| - 4 = 16
2|x + 8| = 20
|x + 8| = 10
x + 8 = 10 or -(x + 8) = 10
x = 2 or x = -18
The solution to the absolute value equation 2|x + 8| - 4 = 16 is x = 2 or x = -18
