 Hello, I am welcome to the session. I am Deepika here. Let's discuss the question it says. A homogeneous differential equation of the form dx over dy is equal to x of x over y. Can be solved by making the substitution A, y is equal to vx, B, v is equal to yx, C, x is equal to vy, D, x is equal to v. Let's start the solution. Now, if the homogeneous differential equation is of the form x over dy is equal to h of x over y. Then the substitution x over y is equal to v is made that is x is equal to vy and which is our option C. Hence the answer for the above question is C. I hope the solution is clear to you. Bye and take care.
