二元一次方程组在实际问题中的应用

摘要

Based on practical cases, this paper focuses on the five measures of system of linear equations of two unknowns in solving practical problems. The cultivation of students' modeling thinking can help them better solve practical problems, which is also the value and purpose of this paper.%　　本文以实际案例为依托，着重从解题思路和解题过程中折射出运用二元一次方程组解决实际问题的五大步骤。通过这种定型化思维的培养，使学生养成用数学建模思想和方程思想来解决生活中的实际问题的思维过程，这也是本文的价值和目的所在。
