Question

1. Which one among the following is not a linear equation? a. x2=18 b.3y = 27 c. p +q= 7 d. x- 10 = -1​

Answer 1

Answer:

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.
