The corresponding point of a rational number on the number axis is a. move point a three unit length to the left and then two unit length to the left to get point B. the absolute value of the number corresponding to point B is equal to that of point A. what is the corresponding number of point a?

Let the number corresponding to point a be x, then the number corresponding to point B x-3-2 = X-5, and the absolute value of the number corresponding to point B and the number corresponding to point a are equal, | x | = | X-5 |, the solution is: x = 2.5
