I just seem to get this question! Any help would be appreciated!

If y = (x+2)/(x-3) then which of the following represents x?

A. (3y+2)/(y-1)
B. (3y+2)/y
C. (3y-2)/(y+1)
D. 5y/(y+1)
E. (3y-2)/(y-1)

The answer is A but I don't know how to get to it. Please help!
Thanks!

easy

y = (x+2)/(x-3)
y(x-3) = x+2
xy -3y = x+2
xy - x = 3y +2
x(y-1) = 3y+2
x = (3y+2)/(y-1)

done
