章节大纲

  • In the previous chapter, we discussed linear equations and inequalities where an expression was compared to a fixed quantity. However, sometimes when we change one quantity that causes a change in another quantity. We need two variables in our equations and inequalities to model situations like this.
    ::在前一章,我们讨论了线性方程和不平等问题,其中将表达与固定数量作比较。然而,有时当我们改变一个数量导致另一个数量的变化时,我们需要两个变量来模拟这种情况。
