The absolute value symbol |x|, means that x can be either negative or positive, but the absolute value of it will be the positive value. For this question, |x| = 3, we know that the absolute value of x is 3, but the value of x can be either 3 or -3. Once the absolute value is taken, you always get the positive number.
