Solve |x| =1 (that's all it says)
How do I do this? I believe the answer is -1 and 1, but I need to explain how I got this answer.

|x| =1
To find the solution, you need to know what |x| means.
|x| means the absolute value of x. In other words, it is the positive value of x.
|4| = 4
|20| = 20
|-44| = 44
Now that you know what |x| means, we can solve this question.
|x| = 1
x can be 1 as well as the polar opposite of 1.
So, x = 1, -1 is the solution

1=1
Is correct. Absolute value.
For example if you have x= -6 then x will be x= 6
A negative becomes positive and a positive stays positive.

the answer is only positive one. this symbol " | | " means absolute value, meaning always positive.
