The application of one-dimensional equation solving is the focus and difficulty of the first generation number. In recent years, all kinds of junior high school math competitions often examine this part of the content, in order to help the students to calmly challenge, this article selects a series of one-element equation solving problems. Examples: There are eight examples in the textbook, which represent the eight types that we should master: the sum of multiples, the problem of shape product, the problem of meeting, the problem of recruitment, the problem of labor deployment, engineering problems, the problem of profit of goods, and many Number problems. Looking at various types of junior high school math competitions in recent years, list one yuan at a time
