Linear Equation

 
Question

What is a linear equation? 

Solution

Any equation of the first degree is known as a linear equation.

Linear equation in one variable
It is an equation of the form ax + b = 0, a
0,
where a and b are constants and x is a variable.

ax + b = 0

is known as the solution or root of the equation ax + b = 0.

 
Example

Consider the following equations: 

1)2x + 1 = 0, 

Solution

The root of the equation is x = -

 

 

Example

3x - 2 = 0,

Solution

The equation is x = or it is called the root of the equation.


 

Example

4x +7= 3

Solution

The solution of this equation is 4x = 3 – 7

x =

is the root of the equation.

 

 

POINTS TO NOTE

The solution of a linear equation is not affected when

1)the same number is either added or subtracted from both sides of the equation.

2) the same non-zero number is multiplied or divided on both sides of the equation.
