Answer:
Option A and Option E
Step-by-step explanation:
Option A.
x + 3 = 5
(x + 3) - 3 = 5 - 3
x = 2
Option B.
x + 2 = 8
(x + 2) - 2 = 8 - 2
x = 6
Option C.
x + 1 = 1
(x + 1) - 1 = 1 - 1
x = 0
Option D.
x - 2 = 4
(x - 2) + 2 = 4 - 2
x = 2
Option E.
x - 7 = -5
(x - 7) + 7 = -5 + 7
x = 2
Therefore, Option (A) and Option (E) are the correct options.

An ordered set of mathematical objects is called a pattern.
