Many real life problems can be solved by converting a problem into a mathematical equation but some problems like the height of all the members in your family is less than 180 cm, auditorium can occupy at most 120 tables or chairs or both can't be converted into equations. Statements which involve sign ‘’ '>' (greater than), ‘≤’ (less than or equal) and ≥ (greater than or equal), '<' (less than) are known as inequalities. T he concept of inequality is used in formulating the constraints. In NCERT solutions for class 11 maths chapter 6 linear inequalities you will understand questions based on inequalities in one variable and two variables.

**Inequation (Inequality):**

An inequation or inequality is a statement involving variables and the sign of inequality like >, <, ≥, or ≤.

**Symbols used in inequalities:**

The symbol < means less than.

The symbol > means greater than.

The symbol < with a bar underneath ≤ means less than or equal to.

The symbol > with a bar underneath ≥ means greater than or equal to.

The symbol ≠ means the quantities on the left and right sides are not equal to.

**Algebraic Solutions for Linear Inequalities in One Variable:**

Linear inequalities involve expressions with variables and inequality symbols like <, >, ≤, or ≥.

The solution to a linear inequality can be determined using algebraic methods.

Important rules to follow when solving linear inequalities:

Rule 1: Don’t change the sign of an inequality by adding or subtracting the same integer on both sides of an equation.

Rule 2: Add or subtract the same positive integer from both sides of an inequality equation.

**Graphical Representation of Linear Inequalities:**

Linear inequalities can also be represented graphically on a number line.

For example, x > 3 represents all real numbers greater than 3, which can be shaded on the number line to the right of 3.

Similarly, x ≤ -2 represents all real numbers less than or equal to -2, which can be shaded on the number line to the left of -2.

Definition of Inequality: An inequality is a statement that two values are not equal. In mathematics, inequalities are used to compare values and to represent constraints in real-world problems.

Linear Inequalities: Linear inequalities are a type of inequality where the variables appear only in the first degree, that is, raised to the power of 1.

Solving Linear Inequalities: The process of finding all the possible values of the variable that satisfy a given linear inequality is called solving the inequality. In this chapter, various methods of solving linear inequalities are discussed.

Graphical Representation: Graphical representation is an important tool to visualize the solution of a linear inequality. The chapter 6 class 11 maths discusses how to plot linear inequalities on a coordinate plane.

Solution of System of Linear Inequalities: The NCERT solution for class 11 maths chapter 6 also discusses the solution of a system of linear inequalities, which involves finding the region on the coordinate plane that satisfies all the inequalities in the system.

Application in Real-World Problems: Linear inequalities are widely used in real-world problems, such as optimizing production, minimizing costs, and maximizing profits. The chapter provides various examples of real-world problems that can be solved using linear inequalities.

A manufacturing unit makes two models p and q of a product. Each piece of p requires 9 labour hours for fabricating and 1 labour hour for finishing. Each piece of q requires 12 labour hours for fabricating and 3 labour hours for finishing. For fabricating and finishing, the maximum labour hours available are 180 and 30 respectively. The manufacturing unit makes a profit of Rs 8000 on each piece of p and Rs 12000 on each piece of Model q. Formulate this problem in linear equalities to maximize the profit.

The above problem can be formulated using linear inequalities and can be solved using linear programming which you will study in NCERT solutions for class 11 maths chapter 6 linear inequalities.

**The above problem is formulated as follows. **

**Let x is the number of pieces of Model p and y is the number of pieces of Model q **

We have to maximize the profit Z= 8000x+12000y subjected to the following constraints
