What is a combination of more than one inequality?

A combination of more than one inequality is known as a system of inequalities. This system consists of two or more inequalities that are considered together, and the solution is typically the set of values that satisfy all the inequalities simultaneously. Graphically, this can be represented as the overlapping region of the graphs of the individual inequalities. Systems of inequalities are often used in optimization problems and to describe constraints in various fields such as mathematics, economics, and engineering.
