A Linear inequality with a variable is the type of inequality, where they are real numbers. If, the linear linear is also called first degree inequality.
In general, to solve any system of inequalities, we trace, in the same coordinate system, the region that represents the solution of each of the inequalities that make up the system. The system solution will then be given by the intersection of these regions. The following two scenes show examples of systems of inequalities involving linear and quadratic inequalities.
