I think my first step is to get the y's and dy on one side, and the t's and dt on the other
\[(7/y) dy = t - (1/t) dt\]
try \(y=at^2\)

From the start or where I left off?
From the start. A good guess for the function is some power of t, \[y(t) = a\cdot t^b \] If you plug that in, you'll find that \(b=2\) as Zarkon said, but you'll also find what \(a\) has to be.
