这两周我们学习了一元一次方程的应用，主要有工程、行程问题；调配问题；等

In the past two weeks, we learned the application of one-dimensional linear equations, mainly including engineering and itinerary issues; allocation issues; grade deformation; interest rates and commodity sales issues. Among them, engineering issues and schedule issues involve more complex issues, and some students may find it difficult, but encourage children to try the methods taught in class and practice more at home.

In the past two weeks, we have learned the application of univariate linear equations, mainly engineering and travel problems; Deployment issues; Grade deformation; Interest rate and commodity sales. Among them, the problems involved in engineering problems and travel problems are more complex. Some students may feel difficult. They still encourage children to try using the methods taught in class and practice more at home.

In the past two weeks, we have studied the application of unary linear equations, mainly including engineering and trip problems. Allocation problem; Grade deformation; Interest rate and commodity sales problems. Among them, the problems involved in engineering and itinerary are complicated, and some students may find it difficult. They should encourage their children to try using the methods taught in class and practice more at home.
