## Notes

The solution of a linear inequalities is the graph of common solution of the system. It is the ordered pair of all inequalities.
So the solution of the system of linear inequalities could be:
1) Graphical
2) Non Graphical
1) Graphical Method :- It is the easiest method in solution of the system of linear inequalities.In this process of making graph is similar to the graph of linear imequalities in two variables.
2) Non Graphical: There is no need to make a graph but we can find the solution of the system of inequalities .
