谁能帮我翻译一下这道题:

the ratio of goods to bads was 2 to 5 and the number of bads exceeded twice the number of goods by 40. How many were good and how many were bad?

好与坏的比例是2:5。坏的数量比好的数量的两倍多40。好的有多少?坏的有多少?
设goods为X,那么bads就是2X+40
X / (2X + 40)= 2 / 5
X = 80, 2X + 40 = 200
Goods were 80; and bads were 200.
