Let u = {2,3, a ≠ 2a-3}, a = {| a + 1 |, a} CUA = {5}, find a Let u = {2,3, a ≠ 2a-3}, a = {a + 1}, 2}, CUA = {5}, find a

Let u = {2,3, a ≠ 2a-3}, a = {| a + 1 |, a} CUA = {5}, find a Let u = {2,3, a ≠ 2a-3}, a = {a + 1}, 2}, CUA = {5}, find a

First of all, the restriction is that a ^ 2 + 2a-3 cannot be equal to 2 or 3, and | a + 1 | cannot be equal to 2
In fact, first do not care about it, and finally come to the answer, and then verify with
Then we have to discuss it
Case 1: A ^ 2 + 2a-3 = | a + 1 | and a + 3 = 3
Not established
Case 2: a + 3 = a ^ 2 + 2a-3 and | a + 1 | = 3
A = 2
The answer is a = 2
