现行初中数学教学大纲已明确强调学生要通过学习数学“能够运用所学知识解决简单的实际问题”,并将实际问题界定为“带有实际意义的和相关学科中的数学问题,以及解决生产和日常生活中的实际问题“.为了迎合大纲的要求和发展素质教育,近年来,中考应用题除沿袭传统的工程、行程等问题外,更大程度上向日常生活、实际应用问题倾斜.现就一元一次方程在实际生活中的应用,举一此常见例子. The current junior high school mathematics syllabus has clearly emphasized that students must “be able to use the knowledge they have learned to solve simple practical problems” by learning mathematics, and define practical problems as “mathematical problems with practical and related disciplines, as well as solutions to production and "In order to meet the requirements of the syllabus and develop quality education, in recent years, in addition to traditional engineering and itinerary problems, the questions applied in the senior high school entrance exams have been more inclined to everyday life and practical application problems. The application of a one-dimensional equation in real life gives a common example.
