This is a tutorial on solving systems of inequalities with two variables.Examples with detailed explanations are presented. In order to solve a system of inequalities, we first solve graphically each inequality in the given system on the same coordinate system and then find the region that is common to each solution (which is a region) of the inequality in the system: it is the intersection of ...
On the other hand, systems of two linear inequalities in two variables can only be solved graphically. Specifically, we graph each inequality in the same Rectangular Coordinate System. The solution set of the system will then be the overlapping region of the individual solution sets of the two inequalities.
Linear inequalities in two variables represent the unequal relation between two algebraic expressions that includes two distinct variables. Hence, the symbols used between the expression in two variables will be ‘<’, ‘>’, ‘≤’ or ‘≥’, but we cannot use equal to ‘=’ symbol here. The examples of linear inequalities in two ...
Solutions to Systems of Linear Inequalities. A system of linear inequalities consists of a set of two or more linear inequalities with the same variables. The inequalities define the conditions that are to be considered simultaneously. For example,
Some of the linear inequalities in two variables are: ax + by < c. ax + by > c. ax + by ≤ c. ax + by ≥ c. ax 2 + bx + c ≤ 0. ax 2 + bx + c ≥ 0. These are linear inequalities in two variables x and y when a ≠ 0, b ≠ 0. A system of linear inequalities in two variables consists of two or more linear inequalities containing the same ...
where A is an m×n matrix, x is an n×1 column vector of variables, and b is an m×1 column vector of constants. In the above systems both strict and non-strict inequalities may be used. Not all systems of linear inequalities have solutions. Variables can be eliminated from systems of linear inequalities using Fourier–Motzkin elimination ...
A system of linear inequalities in two variables consists of at least two linear inequalities in the same variables. The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the linear inequality is the graph of all solutions of the system.
To create a system of inequalities, you need to graph two or more inequalities together. Let’s use [latex]y. 2x+5[/latex] and [latex]y>−x[/latex] since we have already graphed each of them. The purple area shows where the solutions of the two inequalities overlap. This area is the solution to the system of inequalities.

In Section 4.4 on linear inequalities in one variable, we saw apowerfulmethod for keeping track of solutions of algebraic statements with infinitely many solu-tions: graphing. However, in the case of ...
Example 2: Graph a Linear Inequality in Two Variables (2 of 5) Step 2 continued We find that the intercept method did not result in two data points ... and without two data points we cannot graph a line. Let’s use the Point-by-Point Plotting Method to find the coordinates of two other points. Let's use x = 2, then 3y = – 9(2) and y = – 6 ...
Solutions of a System of Linear Inequalities: Solutions of a system of linear inequalities are the values of the variables that make all the inequalities true. The solution of a system of linear inequalities is shown as a shaded region in the x, ycoordinate system that includes all the points whose ordered pairs make the inequalities true.
The solution of a linear inequality in two variables like Ax + By > C is an ordered pair (x, y) that produces a true statement when the values of x and y are substituted into the inequality. ...

A system of two linear inequalities is shown here. \[\left\{\begin{aligned} x+4 y & \geq 10 \\ 3 x-2 y & <12 \end{aligned}\right. \nonumber \] To solve a system of linear inequalities, we will find values of the variables that are solutions to both inequalities. We solve the system by using the graphs of each inequality and show the solution as ...
