Question

How do you solve `|x|=11`?

Answer 1

`x=pm11`

Explanation:

The absolute value sign (the two vertical lines that the `x` is sitting between) means that whatever the value of `x` is, whether positive or negative, it will be positive when the absolute value operation is performed.

For instance, if `x=11`, then

`abs11=11`

However, if we set `x=-11`, then

`abs(-11)=11`

And so `x` can be 11 and `-11`.
