What is the solution set of {x | x > -5} u {x | x < 5}?

•all numbers except -5 and 5
•the empty set
•all real numbers

For this case we must find the solution set of the following inequalities:

The solution is given by all values of x greater than -5.

The solution is given by all values of x greater than -5.

Then, the solution set is given by all real numbers.

The solution is given by all real numbers.
