Equation $y'=\frac{y-t}{y+t}$ is
linear and separable
linear but not separable
separable but not linear
None of the above
My answer is D. But it could have been C. One more?
Solution As written, this seems to me to be neither linear nor separable. However, this is a homogoeneous equation that reduces to a separable equation by substitution $y=v t$. (This substitution appears in exercise 25 for section 2.2.)
