1. Given that the absolute value of equation x = ax + 1 has a negative number solution but no positive number solution, find the value range of A 2. If a, B and C are all integers, and the absolute value of A-B to the 19th power plus the absolute value of C-A = 1, then what is the absolute value of C-A plus the absolute value of B-C plus the absolute value of B-A
