Work Step by Step

A system of linear inequalities is a collection of linear inequalities that need to be satisfied SIMULTANEOUSLY. For example, in two variables, each inequality of the system may have the form $Ax+By > C,$ $Ax+By \geq C,$ $Ax+By < C$, or $Ax+By \leq C$. In three variables, each inequality of the system may have the form $Ax+By+Cz > D,$ $Ax+By+Cz \geq D,$ $Ax+By+Cz < D$, or $Ax+By+Cz \leq D$ In four variables ... etc.
