Order the steps: solve by separating variables

Read exercise and reference answers
Steps
  1. Check that x and y terms can be separated completely
  2. Move every y term to the side carrying dy
  3. Move every x term to the side carrying dx
  4. Integrate both sides
  5. Add the arbitrary constant to obtain the general solution
