Differential equations question - possible integrating factor?

Click For Summary
SUMMARY

The discussion centers on solving the differential equation 3e5xdy/dx = -25x/y2 with the initial condition y(0) = 1. The initial attempt involved separating variables, but the user encountered an error when submitting the solution. The conversation clarifies that while integrating factors are typically used for linear equations in the form dy/dt + a(t)y = r(t), this equation is separable, confirming that the initial approach is valid. The user is encouraged to show their work for further assistance.

Homework Statement



Solve the differential equation with the initial condition y(0) = 1

Homework Equations



3e5xdy/dx = -25x/y2

The Attempt at a Solution



First I tried putting everything with an x or dx on one side and a y or dy on the other side, and solved for C. I got 0 as the constant, but when I plugged it into the online homework system it said I was wrong.

I thought about using an integrating factor, but that can only be used when the equation is in the form dy/dt + a(t)y = r(t), right? Meaning I can't use it here because there's a y2 instead of a y?

The equation is separable, so your first approach is the right one. Can you show some of your work?
