Answer:

B. x=2wy+y-1

Explanation:

The given equation is

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

We multiply through by y

$\implies y * (2x+2)/(y)=y(4w+2)$

$\implies 2x+2=y(4w+2)$

Moreover,we expand the parentheses at the right side of the equation to get

$\implies 2x+2=4wy+2y$

we then subtract 2 from both sides of the equation to arrive at

2x=4wy+2y-2

we finally divide through by 2

(2x)/(2)= (4wy)/(2)+ (2y)/(2)-(2)/(2)

$\implies x=2wy+y-1$

Therefore the value of x=2wy+y-1
