Chapter 3- linear Equation

**Learn about linear equations and related concepts!**

**What is linear Equation?**

An equation of form ax + by + c = a, where a, b, and c are real numbers such that a and b are not zero is called linear equation in two variables.

It has infinite solutions.

The graph of the linear equation is always straight line x=a is a straight line parallel to the y-axis and y=b is the straight line parallel to the x – axis.

And every solution of the linear equation is a point on the graph of the linear equation.

The ScoreX^{TM} provides the best study material **CBSE class 10 maths chapter 3** which is easy to learn and understand.

**What is the format of the course?**

In the course of **CBSE class 10 math chapter 3, **we cover all the main topics. Some are:-

Algebraic methods of solving a pair of linear equations are as follows:-

· **Substitution method** - In this method, we can substitute the one value with another value.

· **Elimination method** - In this method, we eliminate one of the two variables to obtain an equation in one variable which can be easily solved.

· **Cross - multiplication method** - In this method, we have to put the values of a1, a2, b1, b2, c1 and c2. and by solving it, we will get the value of x and y.

**Graphical representation of lines **

1. Intersecting lines

2. Parallel lines

3. Coincident lines
