​  

 

Here, only one variable is given and highest order of the variable is 1. Therefore, this is a linear equation in one variable.

Consider the given equation.

x+3y=5

Here, highest degree of the variables is 1, but there are two variables, x and y. Therefore, this is not a linear equation in one variable.

Consider the given equation.

a=0

Here, only one variable is given and highest order of the variable is 1. Therefore, this is a linear equation in one variable.
