  • 导言:线性等同和不平等制度

    In the previous chapter, we considered one linear model at a time. But there are many applications where we want to consider how two or more linear models interact with one another. For example, how the costs and the revenue of a business compare or how to come up with the best combination of foods for your diet given restrictions on certain nutrients.
    ::在前一章中,我们一次考虑过一种线性模式。但有许多应用,我们想考虑两种或两种以上线性模式如何相互作用。例如,企业的成本和收入如何比较,或者鉴于某些养分受到限制,如何找到食物的最佳组合。

    These are examples of systems of equations , a group of equations or inequalities that we consider together. We study them in this chapter.
    ::这些是等式体系、一组等式或我们共同考虑的不平等等式体系的例子,我们在本章中加以研究。

    By the end of this chapter, you should be able to:
    ::在本章末尾,你应当能够:

    • Identify types of systems of equations.
      ::确定方程式系统的类型。
    • Solve a system of equations by graphing, substitution, or elimination by addition.
      ::通过图表绘制、替代或加法消除等方程式系统。
    • Solve a system of linear inequalities by graphing.
      ::通过图形化解决线性不平等系统。
    • Solve a system of three linear equations algebraically.
      ::解决一个由三个直线方程式代数组成的系统。
