When Xiao Ming woke up, he found that the whole world was wrong. He always forgot to take his books from school and had to wait until his father brought them over by bike. After class, he asked Xiao Hong where he bought the pens. Xiao Hong said: "Ah, I forgot. Please help me do the math. I bought 10 pens for 64 yuan, and the price of this kind of pen is twice that of that kind." "When Xiao Ming was buying medicine for his sick father, the drugstore owner asked: "I have red medicine and blue medicine here. There are 100 red medicines and 100 blue medicines. First, give 10 red medicines to the blue medicines, and then give 10 blue medicines to the red medicines. What are the red medicines X and blue medicines Y at this time? "Xiao Ming: Haha. The girl attacks and complains. The author is so logical that he is trying to hide it from me. _(:з∠)_
