If the absolute value of a = 2, then a = how much; if the absolute value of A-2 = 1, then a =; if the absolute value of A-3 = 3-A, then a =

If the absolute value of a = 2,
Then | a | = 2,
The solution is a = 2 or - 2,
If the absolute value of A-2 = 1,
Then | A-2 | = 1,
That is, A-2 = 1 or A-2 = - 1,
The solution is a = 3 or 1
If the absolute value of A-3 = 3-A,
Then there is | A-3 | = 3-a,
That is, A-3 ≤ 0,
Remember a ≤ 3
