(2x+2/Y)=4w+2
2x+2 = 4w+2*Y ---Multiply both sides by Y
2x = 4w*y ---Subtract 2 from both sides
x = 2w*1/2y ---Divide everything by 2
Well, I believe that's the answer.
Like DragonSlayer said, if we have the values of w and y we could solve for x = number, but I think this is how you would solve it not knowing w or y.
