If we need to convert this expression, there's only one option here:
We remove the twos, since.к. We first subtract 2 from X, and then we add.
-2+2=0. This will leave X+X=2X
Answer: X-2+X+2=X+X=2X

Check.
Substitute any number, such as 3 or 20
3-2+3+2=6=2 х 3
20-2+20+2=40=2 х 20

Ask the questions that interest you, even if they seem silly, childish, strange, funny, embarrassing, uncomfortable, or abstruse.
