    Just making sure

    I just want to make sure I'm understanding this right.

    What interval represents the solution set of the inequality |2x-3| (less than or eqaul) 5?

    I've come up with [-1,4]. Am I right or is it supposed to be something like (0,4) or (-infinity, infinity)?

    |2x - 3| \le 5

    -5 \le 2x - 3 \le 5

    -2 \le 2x \le 8

    -1 \le x \le 4

    [-1, 4] is correct
