Question

1
Is the equation a linear equation in 2 variables ?
i) 3x2 - 7y = 13​

Answer 1

Answer:

no , it's not linear equation

Step-by-step explanation:

3x^2 -7y= 13 includes the index value of 2 which means the quadratic equation whereas condition is that its must be linear equation ,so it's not linear equation

Answer 2

3x² - 7y = 13 is not a linear equation in 2 variables

Given :

The equation 3x² - 7y = 13

To find :

To check the equation is a linear equation in 2 variables

Solution :

Step 1 of 3 :

Write down the given equation

The given equation is 3x² - 7y = 13

Step 2 of 3 :

Find the number of variables

In the equation 3x² - 7y = 13 the variables are x and y

So the number of variables is 2

Step 3 of 3 :

Check whether the equation is a linear equation or not

In the equation 3x² - 7y = 13 the power x is 2 and the power of y is 1

So the highest power of its variable that appears with nonzero coefficient is 2

Hence 3x² - 7y = 13 is not a linear equation in 2 variables
