在初中学习和教学中,很多时候我们可以用不同的知识进行对比学习和教学,对于解一元一次不等式类似解一元一次方程都是通过性质来进行求解,但等式的性质2在不等式中分成了两条性质区分乘除数的正、负符号,这一点也是在解不等式时容易忽视的地方。现在对解一元一次方程与一元一次不等式进行对比便于区分. In junior high school learning and teaching, many times we can use different knowledge to compare learning and teaching, for solving a unary inequality similar solution to a linear equation is through the nature of the solution, but the nature of the equation 2 in the inequality into The two properties distinguish between positive and negative signs of multiplication and division, which is also a place easily overlooked when solving inequalities. Now it is easy to distinguish between the solution of a linear equation and the unary inequality.
