Question

which of the following equation is not a linear in one variable (a)x+4=21 ( b) 2x+4=x (c) 3 t =1 (d) x+3=y​

Answer 1

Answer:

Consider the given equation.

2x−1=

2

3

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.
