Answer 2

it is the right side

Answer 3

well my dad said it was line 2 but it isnt an answer choice

Answer 4

your dad is right! since \(4x-4x-2=-2\) and not \(2\), so the second line is:
\(4x-6=-2\)

Answer 5

but it isnt an answer choice so what do i do

Answer 6

maybe there is a typo in the numeration is wrong, namely
the first line is: \(8x-6=4x-2\), so the second line is \(8x-4x-6=4x-4x-2\)
and the third line is \(4x-6=2 \), and so on...
