Section outline

  • In this chapter, we will consider algebraic statements—equations and inequalities. Particularly, we will focus on solving equations and inequalities. That is, we will discuss how to find a value or values for a linear equation or inequality that makes both sides of the  equation equal or that satisfy the inequality relationship.
    ::在本章中,我们将考虑代数说明——公平与不平等——特别是,我们将侧重于解决等式和不平等问题,也就是说,我们将讨论如何为线性等式或不平等找到一种价值或价值,使等式的两面都平等或满足不平等关系。

    There are many practical applications for equations and inequalities of one variable, including determining the amount of sales tax, the range of  miles per gallon for a hybrid car, and when your cell phone is in a wireless roaming area.
    ::一个变量的方程式和不平等有许多实际应用,包括确定销售税额、混合汽车每加仑的里程范围以及手机在无线漫游区时。
