1. Xiaoxiaojia bought the same number of apples and pears. She ate four apples and two pears a day. After a few days, there were eight pears left. The apples were just finished. How many apples and pears were there? 2. There are the same number of comic books and science fiction books. 39 comic books and 27 science fiction books are loaned out every day. After a few days, the comic books are just finished, and there are 48 science fiction books left. How many days have they been loaned?
1. Let's eat for X days and get the equation: 4x = 2x + 8
The solution is: x = 4
Apple: 4 * 4 = 16
Raw pear: 2 * 4 = 8
2. Let's borrow a total of X days. According to the meaning of the question, we get the equation: 39x = 27x + 48
The solution is: x = 4
