Key Takeaways. To graph solutions to systems of inequalities, graph the solution sets of each inequality on the same set of axes and determine where they intersect. You can check your answer by choosing a few values inside and out of the shaded region to see if they satisfy the inequalities or not.
What is a system of inequalities. Learn how to solve and graph it with examples.
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 a graph.
A system of linear inequalities looks like a system of linear equations, but it has inequalities instead of equations. A system of two linear inequalities is shown here. {x + 4y ≥ 10 3x − 2y <12. To solve a system of linear inequalities, we will find values of the variables that are solutions to both inequalities.
Graph the solution set of a system of two-variable linear inequalities with more than two inequalities. A linear inequality is the same as a linear equation Ax + By = C, but with the equal sign replaced with an inequality sign. An example is 2x − 3y ≤ 4. Often a linear inequality is written in “slope-intercept form,” for example y ≤ x ...
The solution set of a system of inequalities is often written in set builder notation: \[\{x \mid x<0\ \cup\ x>6\},\] which reads "The set of all \(x\) such that \(x\) is less than 0 or \(x\) is greater than 6." Systems of inequalities can also be denoted with interval notation.

The solution to the system of linear inequalities is the region of the plane where all of the individual lines' shading overlaps. This solution region is the intersection of the various lines' shadings; it is the area of the graph where all the inequalities are "happy".
Step 1: Solve each inequality separately. Step 2: Find the common values between the two inequalities. (Use a number line if necessary) Example: Solve the following simultaneous inequalities and represent your solution set on the number line. x + 2 < 6 and x – 3 > – 1. Solution: x + 2 < 6. x < 6 – 2. x < 4. x – 3 > – 1. x > – 1 + 3. x > 2.
