the first one,2/(2-2x2)+2=1

the 2nd one,2/(2-2)x2+2=undefined

the 3rd one,(2/2-2)x2+2=0

the 4th one,2/2-(2x(2+2)=-7........[the answer of that question]

2 / 2 − ( 2 × ( 2 + 2 ) ) = 1 − ( 2 × ( 2 + 2 ) ) = 1 − ( 2 × 4 ) = 1 − 8 = − 7 2/2-(2\times(2+2))=1-(2\times(2+2))=1-(2\times4)=1-8=\boxed{-7}

It's quite simple to just try all the options.

If you like to do it that way it it fine, but the -7 should give you an indication of the position of the brackets.
