You can put this solution on YOUR website! Assume the problem is: +y = 2y-2
multiply both sides by 2 to get rid of the denominators, results:
9 + 5y = 2(2y-2)
9 + 5y = 4y - 4
5y - 4y = -4 - 9
y = -13

Check this in the original problem +(-13) = 2(-13)-2 - = -26 - 2
4.5 - 32.5 = -28
-28 = -28; confirms our solution of y =-13
