解方程的实质就是利用等式的性质把现有的方程变为x=?,也就是让方程的左边只剩下未知数x。为此,我们经常采用以下手段:一是在方程的两边都加上或减去同一个适当的数;二是在方程的两边都乘或除以(除数不为0)同一个适当的数。下面通过一个例题来看看具体的实施过程:解方程:3x+5=8……① The essence of solving the equation is to use the nature of the equation to change the existing equation to x = ?, that is to say leaving only the unknown x to the left of the equation. To do this, we often use the following measures: one is to add or subtract the same appropriate number to both sides of the equation; the other is to multiply or divide by (divide by zero) the same appropriate number on both sides of the equation. The following example to see through a specific implementation process: Solution equation: 3x +5 = 8 ...... ①
