Question

Which of the following is a linear equation in one variable?

Answer 1

Answer:

Answer:The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers and x is a variable and has only one solution. For example, 2x+3=8 is a linear equation having a single variable in it. Therefore, this equation has only one solution, which is x=5

Answer 2

Linear equation in one variable is an equation which are in the form of ax+b=0.

Explanation:

Linear equation in one variable are the equations which can be expressed in the form of ax+b=0 , where a is an integer( negative or positive integer) and it is said to be coefficient of x , x is a variable which has only only solution, and b is also an integer (negative or positive).

Linear equation in one variable have only one solution. They are the basic equations used to solve unknown quantity.

Example:- $x-6=0$            (this is a linear equation in one variable)

               $x=6$

They are very basic equations which makes them very easy to solve equation.
