在初一,我们学习了一元一次方程,到初二,我们又要学习一元一次不等式.一元一次不等式与一元一次方程有许多类似之处,也有一些不同的地方.从概念上来看,一元一次方程是用等号连接两个含同一个未知数的一次整式所得的等式;一元一次不等式则是用不等号连接两个含同一个未知数的一 In the first day, we learned a one-dimensional equation. By the second day, we must learn a one-time inequality. The one-time inequality has many similarities with the one-ary-one-time equation. There are also some differences. From a conceptual point of view, the one-dimensional equation Is the equality of two integers with the same unknown connected by the equal sign; the one-time inequality is the use of inequalities to connect two ones with the same unknown
