Look At picture! Below!
eimsori [14]

Answer:

The answer is: the second one

Step-by-step explanation:

                                             (2x + 2)/y = 4w + 2

pass y to the right side        2x + 2 = y(4w + 2)

expand                                   2x +2 = 4wy + 2y

pass 2 to the right                2x = 4wy + 2y -2

pass 2 to the right                x = (4wy + 2y - 2)/2

simplify                                  x = 2wy + y - 1 or = 2yw + y -1
