Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

In equation of the form

$\displaystyle \sf{ \frac{dx}{dy} + Px = Q}$

where P and Q are the function of

(A) x only

(B) y only

(C) both A and B true

(D) none of these

EVALUATION

Here the given differential equation is

$\displaystyle \sf{ \frac{dx}{dy} + Px = Q}$

This is a linear differential equation

Here x is dependent variable and y is independent variable

Also P and Q both are functions of y or constants

FINAL ANSWER

Hence the correct option is (B) y only
