Answer 2

as in a stupid example, if i want to prove
x+2/2=x+1
can i do
(x+2/2)-1 = (x+1)-1
x = x

Answer 3

yes looks good to me

Answer 4

the equality is not changed when you add/remove same thing both sides

Answer 5

but in a proof situation that they want you to prove A=B,
in your proof steps are you allowed to do for example A/2=B/2, in order to simplify things
