There are 4 lessons in this math tutorial covering Systems of Inequalities. The tutorial starts with an introduction to Systems of Inequalities and is then followed with a list of the separate lessons, the tutorial is designed to be read in order but you can skip to a specific lesson or return to recover a specific math lesson as required to build your math knowledge of Systems of Inequalities. you can access all the lessons from this tutorial below.

In this Math tutorial, you will learn:

• What are systems of linear inequalities?
• How do we identify the solution set (zone) of a system of linear inequalities?
• Which method is the most suitable for solving systems of inequalities?
• How do we prove the correctness of the solution when dealing with systems of inequalities?
• How do you find the minimum/maximum value of the solution set in systems of inequalities?
• How do you find the leftmost/rightmost value of the solution set in systems of inequalities?
• How do we solve systems of three linear inequalities?
• How do we solve systems of inequalities where at least one inequality is not linear?

## Introduction

Do you remember how to solve a system of linear equations? How many methods we can use for this purpose?

Check whether the following number pair are solutions for the two linear inequalities

3x - 2y > 1 and x + y ≤ 4
A(-2, 0)
B(2, 1)

Do you think there is any simpler method to check whether a number pair is a solution for two simultaneous inequalities? What does this method consist of?
