What are the steps to solve the linear equation of one variable?
(1) It is similar to solving linear inequality of one variable and solving linear equation of one variable, but we should pay special attention to that when both sides of the inequality multiply (or divide) the same negative number, the direction of inequality sign must be changed. (2) to solve the system of inequalities, we usually first find out the solution set of each inequality in the system of inequalities, and then find out their common part
