The ratio of red jelly beans to yellow jelly beans in a dish is 2:3. If I eat 3 red jelly beans and 6 yellow ones the ratos is 4:5. How many yellow jelly beans were orginally in the dish?

r/y = 2/3
(r3)/(y6) = 4/5
r=9 y=13.5
?? is there a typo somewhere? 
No, there is no typo. This is how it was written in the textbook. Thanks for the help. We have been working on this problem for days.

On our worksheet this is the same question, but ours states the original ratio of red to yellow as 3:4.
