    Answer:

    I prefer to express solutions to inequalities using interval notation. Both formats are are important but I think interval notation is easier to understand and represents better the solutions.

    For example, if you have the following inequation:

    x-2> 1

    x>3

    Therefore, the solution could be written either x>3 OR (3, +inf). But what happens if the solution to the system of equation is x>3 or x<-3? The solution can be easily written as: (-inf, -3) U  (3, inf) instead of ‘x>3 or x<-3’ which can be confusing.
