System of Linear Inequalities

A system of linear inequalities is formed when two or more linear inequalities are grouped together to be evaluated at the same time. Structurally, it resembles a system of linear equations, but it features inequality symbols (such as <<, >>, \leq, or \geq) rather than equals signs. For instance, the grouping {x+4y103x2y<12\left\{\begin{array}{l} x + 4y \geq 10 \\ 3x - 2y < 12 \end{array}\right. represents a system of two linear inequalities in two variables. The primary goal of forming such a system is to determine the specific set of ordered pairs that simultaneously satisfy every individual inequality within the group.
