Question

which of the following is not a linear equation with two variable a part 2 X + 3 Y is equals to Zero B part 3 X + 2 Y is equals to zero 3 part 2 X square + 3 Y is equals to zero D part a x + d is equals to zero (I want the full solution) ​

Answer 1

Answer:

C part 2 X square + 3 Y is equals to zero

C.) 2x^2 + 3y = 0 , is not a equation of linear equation in two variables.

Answer 2

Given,

Four equations 2x + 3y = 0, 3x + 2y = 0, 2x² + 3y = 0, ax + d = 0.

To find,

Which among the four equations is not a linear equation in two variables.

Solution,

• If an equation has two unknown variables present in it then it is known as a linear equation with two variables.

• In the equation, 2x + 3y = 0 there are two variables, x which has coefficient 2, and y which has coefficient 3, and hence it is a linear equation in two variables.

• In the equation, 3x + 2y = 0, there are two variables, x which has coefficient 3, and y which has coefficient 2, and hence it is a linear equation in two variables.

• In the equation, 2x² + 3y = 0 there are two variables, x² which has coefficient 2, and y which has coefficient 3, and hence it is a linear equation in two variables.

• In the equation ax + d = 0, there is only one variable x that has coefficient a, and hence it is a linear equation in one variable.

Therefore,  ax + d = 0 is not a linear equation in two variables
