Absolute value describes how far a number is away from zero on the number line. It does not depend on if the number is negative or positive. For example, |5| is 5 points away from zero. In addition, |-5| is 5 points away from zero as well.
An absolute value equation has no solution when the expression is negative, because absolute value is always positive. An equation has one solution when both absolute values have the same sign, positive or negative. An equation has two solutions when the first solution can be changed to negative or positive, which would make a completely new solution.
