1st lesson: One-time-one-time inequality and one-time inequality group Key knowledge points 1. Review of points 1. Use ________ to represent the equation of inequality called inequality. 2. To make ________ the value of an unknown. Let’s call the solution of inequality .3. An inequality containing an unknown inequality ________. The solution set that makes up this inequality. 4. Both sides of the inequality are ________, contain only ________ unknowns, and the maximum number of unknowns is ________, like this inequality , is called the unitary inequality. 5. The ________ of the solution set of each inequality in the unitary inequality group is called the solution set of this unitary inequality group.
