Question 1 Consider the following first order differential equation dy у dx + X =3f(x)/y where f(x) is some given function. Which of the following is true? Your answer: -2/ o Substitution v=y transforms the given equation into a linear differential equation dy V + dx 3х =2f(x). Substitution v=y -2/3 transforms the given equation into a linear differential equation dv V + = 3f(x) dx 2x Substitution v=y7/3 transforms the given equation into a linear differential equation dy V + = 2f(x). dx 3x © Substitution v=y43 transforms the given equation into a linear differential equation dv V + dx 2x = 3f(x).
